Territory: Jalquin

The Jalquin, a Bay Miwok tribelet, controlled the San Leandro Creek watershed from the bayshore to Rocky Ridge. Randall Milliken gives them nearly all of East Oakland southeast of the Sausal Creek watershed to San Leandro Creek and beyond. This was the only Bay Miwok group whose territory included shoreline along San Francisco Bay.

Milliken also claims in A Time of Little Choice that there is evidence the Jalquin and Yrgin were the same people. This is a bit puzzling since he assigns them to different language groups in Native American History Studies for the Los Vaqueros Project: A Synthesis. In that work, as well as in A Time of Little Choice, Milliken unequivocally places the Jalquin among the Bay Miwok. He does not suggest they might have been Ohlone (Coastanoan).

Upper San Leandro Reservoir8 bedrock mortars, 3-5 cupules. Site may be underwater.This is a beautiful spot now because of the Upper San Leandro Reservoir, but it was probably nice in Jalquin times too. Back then these mortars were on a little hillside terrace above Kaiser Creek, a perennial watercourse. How many mortars here and how […]

Camp Confluence

Camp Confluence1 bedrock mortar on the north fork of Kaiser Creek.There’s supposed to be a petroglyph boulder on the upper reaches of Kaiser Creek, but we’ve never been able to find it. We did find this single mortar and little camp though.

Hematite

Hematite Processing Site

Hematite Processing Site12 bedrock mortars at Holy Names College.Hematite was processed and quarried here. It was often burned, which produced brighter reds, and then leached to remove salts and soften the rock. After that it was ground to a powder.Closeup of a chunk of hematite. Subtle processing differences produced different hues of red ochre.This may […]

Hematite Quarry

Hematite QuarryHematite, the mineral form of iron oxide, was highly prized by the Ohlone and Miwok triblets surrounding San Francisco Bay. It was the principal source of red ochre, used in burials, ceremonies, and pigments. Hematite outcroppings near the intersection of Redwood Road and Mountain Boulevard in Oakland undoubtedly supplied much of the prehistoric Bay […]
