Volvon Village on Mallory Creek

Volvon Village on Mallory Creek 715 bedrock mortars and countless housepits spread over a half mile. Cupule rock. This village, located in the highlands of the Black Hills, must have been one of the largest settlements in the prehistoric Bay Area, yet it was, apparently, unknown to early archaeologists and historians. It does not appear […]

Castle Rock Park Partridge Farm area

Castle Rock Park Partridge Farm area7 bedrock mortars and several probable mortarsElevation 2983 ft.This is another site Joel discovered just off Skyline Blvd. near the top of a watercourse.Three mortars on one rock.This rock holds two mortars. The one on top falls into the “probable” category.Go down the hill slope toward the creek to find […]

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 […]

Pond1

Los Vaqueros Pond Village

Los Vaqueros Pond Village130 bedrock mortars and 4 slicks.CA-CCO-461Elevation 642 ft.The pond here is often dry. Nearby Adobe Creek would have provided year-round water to this village.Jim among grinding rocks and housepits.A view of the streamside terrace on the south bank of Pond Village Creek. At least three mortar rocks are visible in this photograph. […]

Morgan Territory Ridge East Shelf #3

Morgan Territory Ridge East Shelf #3Three bedrock mortars.Elevation 1560 ft.We discovered this beautiful funnel-shaped mortar in late Fall 2013.We also found this nice two mortar rock across the swale from the single mortar shown above.

RoundValley5

Round Valley Village

Round Valley Village317+ bedrock mortars, two cupule rocks, and a stacked rock enclosure.CA-CCO-320This settlement is the largest of three that sit along the eastern base of the Black Hills.Joseph Chartkoff in “A Rock Feature Complex from Northwestern California,” American Antiquity, Vol. 48, No. 4, (Oct., 1983), pp. 745-760, notes the similarity between this stacked-rock enclosure […]

Alpine Pond — Palo Alto

Alpine Pond — Palo Alto35 bedrock mortars just below Alpine Pond dam. Look on both sides of the creek.Elevation 2184 ft.A heavy-duty work station on the lip of a steep canyon.We’d like to see signs like this in the tribal lands of the East Bay hills.This rock face is so cool we had to include […]

DI1

Deer Island

Deer IslandTwo bedrock mortars and two anvilsElevation 155 ft.This is another one of Joel’s North Bay discoveries. The mortars are on the other side of this somewhat unpromising-looking rock.Why are mortars conjoined like this? The difference in depth suggests that the shallower one is a “starter” mortar where nuts like acorns are broken up into […]

JaimesKnob3

Jamie’s Knob

Jamie’s Knob13 bedrock mortars.Elevation 445 ft.Thanks to Jaime for turning us on to this great site. It’s just a short 20 minute walk from the end of Snyder Lane. When you go through the gate onto park land take the left-hand, single-track trail. This path conveys you to a private drive bordered by a public […]
