Late Pleistocene and Holocene Bison of the Colorado Plateau.
The most recent comprehensive analysis of Bison distribution in continental North America illustrates an apparent geographic 'gap' of bison records for much of the arid Southwest, especially on the Colorado Plateau (CP; Mc Donald, 1981; Fig. 1). In the western United States, there are well-documented occurrences of Quaternary-aged Bison in physiographic provinces neighboring the CP, such as the Great Basin (Jennings, 1978; Scott and Cox, 2008), southern and middle Rocky Mountains (McDonald, 1981), Wyoming Basin (McDonald, 1981), Arizona deserts (Agenbroad and Haynes, 1975; Wolff, 2013), Bonneville Basin (Madsen et al., 2001), and Rio Grande Rift basin (Harris, 2014).
In recent years, bison from Arizona's House Rock Valley in Arizona have dispersed onto the Kaibab Plateau on the North Rim of the Grand Canyon National Park (NP). Resource managers subsequently questioned the nativity of Bison on the CP and concluded, from lack of evidence and limited tangential environmental assessments (Reimondo, 2012; Huffer, 2013), that bison are not native to the area. These prior studies made no examination of specimens in collections but relied upon published literature. Thus, it is necessary to complete a comprehensive assessment of unpublished accounts of Bison remains from paleontological and archaeological sites that are preserved in local museum collections.
Here, we synthesize the paleontological and archaeological localities known to contain Bison from the Grand Canyon and the surrounding CP along with a few just off the plateau for adjacent references. Our data set includes published and unpublished accounts and unstudied museum specimens along with those records archived in database systems that have recently emerged. Our goal is to address two main questions: 1) when and 2) where did Bison occur on the CP, especially within the Grand Canyon NP and the Greater Grand Canyon Region (as defined in MATERIALS AND METHODS)? We address these questions by assessing, and in some cases describing, museum specimens of Bison from 74 localities on and around the CP (Table 1; Fig. 1). Details about each locality are in the thesis by Martin (2014); we provide only pertinent data herein.
BACKGROUND--Today, there are two, albeit disputed, subspecies of Bison (Cronin et al., 2013): 1) Bison bison bison are historically found in the Great Plains and elsewhere throughout much of North America, and 2) Bison bison athabascae are historically found north of 49[degrees]N latitude in Canada and Alaska. This project does not address subspecies or species but focuses on the animal at the generic level. In all, Bison bison, Bison antiquus, and Bison latifrons have been reported on the CP and in the surrounding provinces (Table 1).
The historical chronicle of bison in the Southwest is complex and confusing. Northern Arizona has scarce historical records, in general, but the Spanish reported a small herd of Bison in the 16th century in east-central New Mexico and adjacent to the CP (Reed, 1952). Native Americans in the 1200s AD and earlier created pictographs and petroglyphs on the walls of Kanab Creek near Kanab, Utah (among other places; Malotki and Wallace, 2011). However, the ideas, memories, and thoughts that inspired these renderings could conceivably have travelled great distances and well beyond the actual zoogeographic distributions, which brings into question the idea that the pictographs and petroglyphs represent local occurrences of bison. A few unrelated, documented occurrences confirm that bison frequented the CP near the Greater Grand Canyon Region in small but self-sustaining herds that most likely had relatively large home ranges to endure the low carrying capacity of the region (Seager et al., 2007).
In 1905, Charles J. "Buffalo" Jones brought bison to the Kaibab Plateau on the North Rim of the Grand Canyon NP (Hoffmeister, 1986) and crossbred them with Bos taurus to create a hardy livestock animal he called "cattelo." In 1906, when Congress established the Grand Canyon Game Preserve, they listed bison as one of the wildlife species that should be maintained on the Kaibab Plateau (unpublished report to U.S. Congress, Protection of Wild Animals in the Grand Canyon Forest Preserve). The Kaibab Plateau was described as "ideal for buffalo [Bison], deer and other wild game" and was "to be recognized as a breeding place therefore" (Wakeling, 2006:25). Most importantly, "the Preserve was created on 28 November 1906 by President Theodore Roosevelt and is still in effect. It predates the establishment of the [Kaibab] National Forest [in 1909], Grand Canyon National Park [in 1919], and the Arizona Game and Fish Commission [in 1913]" (Wakeling, 2006:25). In 1909, these bison were relocated east to the House Rock Valley (Marble Platform) because of the creation of the Kaibab National Forest when CJ. Jones moved all but 15-20 animals out of the area. The 15-20 remaining bison became property of James T. "Uncle Jim" Owens and, by 1927, the herd had increased to 98 individuals and was purchased by the State of Arizona via the Arizona Game and Fish Department. Over the past half-century, introduced 'purebred' Bison bison from Oklahoma and Montana have been added to the bison herd to improve its natural resilience (see discussions in Hoffmeister, 1986; Wakeling, 2006).
Throughout the Holocene, Bison abundances spatially varied over most of North America possibly because of hunting and intraspecific competition; yet, the population steadily increased in the Great Plains until European contact when their abundance probably reached their apex (Flores, 1991). This increase in bison might have occurred because of a few conditions including limited trophic-equivalent competition (Flores, 1991); reduced abundance and diversity of presumed predators since the Pleistocene extinction of the dire wolf (Canis dirus), American lion (Panthera atrox), and the giant short-faced bear (Arctodus simus; Flores, 1991); and cooler, wetter climate conditions, which are favorable for grass growth (Wisely et al., 2008; Craine, 2013; Craine et al., 2013). Thus, the observations made by early western explorers (Hornaday, 1889) are likely misleading or at least poorly representative of Bison abundance.
Furthermore, earlier in the Holocene, Bison were less abundant in the Great Plains and were intermittently present in the Southwest (Broughton et al., 2008). There are potentially multiple factors contributing to the seemingly poor fossil record of Bison during the Late Pleistocene and Holocene on the CP. Yet, the region is incompletely studied by Quaternary paleontologists and zooarchaeologists compared with the neighboring provinces, most likely because of its remoteness.
MATERIALS AND METHODS--The Colorado Plateau is an immense physiographic province between the Colorado Rocky Mountains and the Great Basin Desert (Blakey and Ranney, 2008). The Grand Canyon is defined as the geological gorge that incises the Colorado Plateau (Ranney, 2012) and is immediately surrounded by Grand Canyon NP. We define the Greater Grand Canyon Region as the ecosystem of Grand Canyon NP adjacent to the Colorado River corridor and the plateaus immediately rimming the Grand Canyon gorge. This includes the Coconino, Hualapai, Kaibab, Kanab, Uinkaret, and Shivwits plateaus and the Marble Platform. Thus, we also extend the Greater Grand Canyon Region to approximately 80 km beyond the borders of Grand Canyon NP to encompass the habitats of each plateau (Fig. 1).
Each Bison locality on the CP is listed in Table 1 and is numbered consecutively to correspond with the location shown in Figure 1. Undocumented and misidentified specimens from archaeological and paleontological localities are critical to our assessment. These specimens are archived in collections at the Museum of Northern Arizona (MNA), at the Grand Canyon NP, and at the East Tennessee State University Vertebrate Paleontology lab. The previously undescribed specimens consist predominately of dung and skeletal remains from cave, rock shelter, and packrat midden localities. We verified the identification of each specimen and, if necessary, corrected it using Balkwill and Cumbaa (1992), who improved upon identification guides by Lawrence (1951) and Olsen (1960). In an attempt to capture the full extent of variation, Balkwill and Cumbaa (1992) included every postcranial element and provide 192 quantifiable, osteological characters for comparing Bison, represented by 27 individuals of B. bison bison and B. bison athabascae, and Bos taurus, represented by 16 individuals of several breeds including Holstein, Ayrshire, Shorthorn, Longhorn, and Africander. Balkwill and Cumbaa (1992) described specimens of both sexes and of various ages to account for natural variation within Bison and Bos.
Occurrences of Bison were also recovered from the following online data sets: Neotoma Paleoecology Database (NeotomaDB, wwwneotomadb.org); Arizona's Cultural Resource Inventory (AZSite, wwwazsite.asurite.ad.asu.edu/azsite/); and Neogene Mammal Mapping Portal (NeoMap, wwwucmp. berkely.edu/neomap/). Several localities were in the legal format of Township and Range, which creates a large polygon instead of a point and is imprecise when using point data for other site localities. For each site that was in the legal format, we converted the data into the coordinate system by using a centralized datum in the Township and Range overlay (B. Clark, Earth Point: Township and Range--Public Land Survey System on Google Earth, wwwearthpoint.us.; Earth Point Corporation, Kuna, Idaho) in Google Earth Pro (Google Earth Pro, version 220.127.116.117; Google Inc., Googleplex, Mountain View, California) using decimal degrees. The location is less accurate but more precise for geospatial assessment and analysis.
Each locality has a name and numbering system used by the archiving institution and maintained here. As part of this research, we directly radiocarbon dated Bison specimens from two sites, B:16:0461 and Grand Falls. For other sites, the age is first given as reported in the literature (if provided) or archival database. We converted the given age(s) to calendar years BP as a single mean geologic age for geospatial representation (Fig. 2). The calibration of the radiocarbon years was completed using OxCal Online Tool (https://c14.arch.ox.ac.uk/) by employing the IntCal13 curve (Reimer et al., 2013). We assumed the average date of the calibrated age to be accurate, but it should be understood to be imprecise. We provide details including pertinent published references, archival databases, and dating sources for each site when available.
North American Quaternary Chronologies--There are a number of chronologies that are defined by specific metrics and cannot be easily integrated because of the inherent differences of paleontological and archaeological definitions; we define these below (Fig. 3). Each chronology used here is necessary for relating our various paleozoological sites that contain Bison remains. Furthermore, we implemented a climatic representation for understanding the environmental context of each period.
The Pleistocene is divided into biochronological units referred to as North American Land Mammal Ages based on faunal assemblage components. The Rancholabrean Land Mammal Age is defined by the first appearance of Bison south of 55[degrees]N latitude and begins approximately 160,000 years BP (Bell et al., 2004). Furthermore, the Rancholabrean Land Mammal Age terminates 14,000 years BP when the Santarosaean Land Mammal Age begins (see discussion in Barnosky et al., 2014, for Land Mammal Age divisions within the Holocene).
In addition to the mammal ages, archaeological stages were implemented based on North American human cultures in the Southwest (Polyak and Asmerom, 2001). The Pecos Classification was used in this study because it is culturally specific to the CP region and to the Southwest, and it often relates to the specimens we observed in museum collections. The later subdivisions of the Pecos Classification are within modern times. For this study, 850 years BP to today, which includes the formal historic, prehistoric, and protohistoric periods, is considered modern times to illustrate Bison nativity both precontact and postcontact with Europeans in the Southwest.
RESULTS--Herein, we report 74 sites located on or near the CP (with a few on the periphery) that contain Bison. We add 26 localities to the 48 reported in a recent study by Huffer (2013). Moreover, the previous study found that only 16 localities were described from the Holocene, of which 10 were on the CP (Huffer, 2013). In contrast to the Huffer (2013) study, we found 52 sites from the Holocene, of which 40 were on the CP.
Our assessment resulted in the summary data presented in Table 2. We present two sites of interest in and near Grand Canyon NP--B:16:0461 (specimen GRCA 69396) and Grand Falls (specimen MNA V8301; Table 1). We selected these specimens because they were previously insufficiently identified and only relatively dated.
Site B:16:0461, in the Mather Campground area of Grand Canyon NP, was a surface collection that had not been previously reported or identified. It is a lateral half of a proximal phalanx that is identified as Bison sp. because the lateral margin is curved (see Balkwill and Cumbaa (1992) and Martin (2014) for discussion). This sample returned a radiocarbon date (Beta 374436) of 50 [+ o -] 30 years BP (measured radiocarbon age of 100.5 [+ o -] 0.4 pMC).
The Grand Falls specimens represent two nearly complete postcranial individuals deposited 15 m apart in the same arroyo. In collections, these specimens' elements are mostly joined together with consolidant and adhesive. Here, we only describe the right astragalus because it was not treated with consolidant or adhesive. The medial tubercle of the astragalus is on a level with or above the line drawn across the proximal margin of the distal trochlea, as elaborated in Balkwill and Cumbaa (1992). The posterior surface of the astragalus is excavated and extends as far as the lateral margin. Grand Falls was described in the MNA computer database as an arroyo site near the Little Colorado River, which suggests that it is possibly of Pleistocene age. However, radiocarbon dating (Beta 374435) returned an age of 50 [+ o -] 30 years BP (measured radiocarbon age of 102.4 [+ o -] 0.4 pMC). Subsequently, we placed both B:16:0461 and Grand Falls at the beginning of the 20th century (Pueblo V).
DISCUSSION--Much of what we know about bison on the CP is based on historical and modern studies. Although these are valuable resources, they are incomplete and do not explore the prehistoric record. We found that 13 of our newly identified 26 Bison localities (50%) were either previously not identified as Bison or were incorrectly identified as "unknown," "large mammal," or "Bos." Previous studies rarely identified Bison remains from in situ, pre-European contact because it was traditionally thought that Bison did not inhabit the CP. We are particularly intrigued that some researchers identified an in situ, pre-European contact faunal remain as "Bos taurus," knowing that this taxon arrived with the exploration of Spanish conquistadors, approximately 1540 Common Era. We hope to dispel this persistent line of circular reasoning by providing a thorough assessment of Bison on the CP since the latest Pleistocene.
Some hypothesize that the bison found in the Greater Grand Canyon Region were carrion from scavengers, bloat-and-float from upstream Colorado River, or goods traded by peoples. However, it would seem that the pre-Colombian cultural trading of Bison elements might not have been traded long distances but more locally (Cannon, 2001). Reed (1952, 1955) points out that the bison skeletal and artifactual remains found in a pre-Spanish context across the southern CP (Arizona) are likely due to trade connections; albeit, Reed does state that the record of bison ("cibola") provided by the Havasupai Indians in the Grand Canyon probably represents a local procurement and not a trade item (independently described in Garces and Coues, 1900:403, 406).
In addition, Bison are not known to frequent caves and are categorized as low frequenters of such shelters, with no more than 16.9% of all Bison remains found in caves across the contiguous United States (Jass and George, 2010). Thus, finding Bison remains in caves or rock shelters at 45 of 74 (60.8%) sites on the CP appears to be significant because either they were inhabiting the area or they were scavenged from a nearby location. For comparison, approximately 85.7% of bighorn sheep (Ovis canadensis) remains are found in caves (Jass and George, 2010).
CONCLUSION--The direct impact of this study is the production of the first comprehensive review of late Pleistocene and Holocene Bison on the Colorado Plateau. The results indicate that the geographic range of fossil and modern Bison can be extended to include the CP. Our data imply that Bison have been part of the CP from at least approximately 44,000 radiocarbon years ago though the latest Pleistocene (Rancholabrean) to the onset of the Holocene (~11,000 years ago). The past approximately 11,700 years is a critical time because it marks the beginning of the modern climate based on paleobotanical records (McClaran and Van Devender, 1995; Coats et al., 2008). Major ecological and faunal turnover occurred at or by approximately 11,700 years ago, yet the early Holocene climate was still colder than today. The fossil Bison record for the early Holocene is not well-reported on the CP, but there appears to be good evidence of Bison presence during the late Holocene, through the various cultural phases, and up to the time of European contact. The southern CP (south of the Grand Canyon) in Arizona appears to have been fairly devoid of bison; but, within the Grand Canyon (likely just north of the Colorado River) and north, Bison were likely present, albeit never likely abundant based on its record. Though Bison were not overly common, such as observed on the Plains, the fossil record clearly demonstrates that this iconic bovid played a role in the biotic communities over much, if not all, of the Colorado Plateau up to the time of European contact.

Caption: FIG. 1--Map of Bison localities (placement is approximate) on the Colorado Plateau (CP, heavy line) and surrounding region. Locality numbers refer to Table 1. Hashed line represents our definition of the Greater Grand Canyon Region (GGC, see Materials and Methods section) surrounding Grand Canyon National Park (GCNP, shaded area).
Caption: Fig. 2--Map of Bison localities placed in chronological context on the Colorado Plateau (CP, heavy black line) and surrounding region. Hashed line represents our definition of the Greater Grand Canyon Region (GGC; see text). Time unit is in thousands of calendar years ago BP (kya).
Caption: FIG. 3--Integrated North American Quaternary chronology. This time scale displays geological, paleontological (North American Land Mammal Ages: [Bell et al., 2004; Barnosky et al., 2014]), climatic (Climate Regime: Zhao et al., ; Cohen et al., ), and cultural (Pecos Classification: Polyak and Asmerom ) units that are all important for relating Bison localities. Not all units are displayed to scale; some cultural units are enlarged for legibility. The relative temperature (solid line) is represented as a proxy derived from 818-Oxygen isotopes from the Greenland Ice Sheet Project (GISP2). Data from Marine Oxygen Isotope Stages (Anderson et al., 2000); and temperature from GISP2 (Grootes et al., 1993). Abbreviations: ka = kilo annum (thousand years ago); BP, Before Present; CE, Common Era; %, part per thousand.
