T.GB.1859.1 is a Tracks entry which refers to the sighting and general, historical presence of “numerous” grizzly bears on and around Bear Mountain and the Calaveras River system in San Andreas, California, United States, on the 16th of November, 1859.

This microhistory appears in an article (fig. 1, above) published in the California newspapers the San Andreas Independent (19 November, 1859) and San Joaquin Republican which describes local news in San Andreas. It describes the presence of multiple human actors in proximity to a community of grizzlies in seasonal transition from hyperphagia to the “predenning” or denning behaviours of autumn which precede and relate to the winter rest period (also called torpor sleep, or “hibernation”) which begins in late autumn or early winter and continues throughout the subsequent winter.¹

The article describes several associated weather events and elements in both the California Interior Chaparral and Woodlands and Sierra Nevada Forests ecoregions, and the related Mediterranean Forests, Woodlands and Scrub biome. It divulges relationships between this microhistory and rain, local flooding, and a resulting, high water table potentially involving snow runoff triggered by unseasonably warm temperatures. It refers to the presence of relevant prey species such as deer and “large game,” and its geographic details suggest den site features relevant to modern Grizzly populations, including proximity to fresh water, thermal cover, and a protected den aspect, offering further potential context concerning the elevation and slope of historical den site relationships. The article postulates relationships between heavy snow at higher altitude and animal movement “down to the snowless [regions]” in closer proximity to American settlement.²

While the suggestion of these seasonal behaviours in this microhistory adds plausibility to the presence of adult predators, the relationship of this community or its individual members to maternity, health (including length and weight data), and sex distribution are neither stated nor inferable from context. 

The article demonstrates several intersections with extractive industries, including mining and prospecting which divulge the local presence of associated mining infrastructure and settlement, as well as the adjacent water management activities of the Calaveras Water Company. This microhistory’s reference to the prospecting activities of Mark McNicholas and unnamed “others” (specifically, the party’s discovery of gold at the summit of Bear mountain) may offer context to the history of GB.1859.1, a Grizzly killed in the same location at the same time, but whose fatality is not reported in this article. T.GB.1859.1 represents neither a relationship to human fatality nor human injury, and is not known to involve domestic or companion animals, or livestock animals.

Importantly, the article’s disclosure of the location of a predator population or community and the availability of large “game” on the Calaveras River and in the Sierra Nevada Mountains to other area hunters should be read in dialogue with the history of the California Grizzly, an extinct sub-type of Grizzly or North American Brown Bear with critical relationships to 19th Century settlement, ranching, and hunting. Its description of “bears” alongside its mention of “grizzlies” may suggest the presence of the American Black Bear and its associated subtypes.³ Should future context support this, the interlinkage of this microhistory with both T.GB.1859.2 and GB.1859.1 may suggest a historical incidence of sympatry, an ecological condition which describes the presence of two distinct but related species in the same environment, potentially encountering one another as a result of their overlapping habitats.

The later microhistory T.GB.1859.2 extends the geographic range of this microhistory towards Salt Spring Valley, a predominantly-French mining settlement southwest of San Andreas near the Bear Mountain Range  in the Sierra Nevada Mountains.⁴

It should be noted that the San Andreas Independent is a particularly difficult source to locate in digital and physical archives. The article which is reprinted in the San Joaquin Republican suggests a publication of the original article on 19 November 1859.
