Geology, Historical Contingency, and Ecological Inheritance in California's Southern Sierra Nevada
The Late prehistoric archaeological record of the Southern Sierra Nevada can be distilled down to two very visible elements: bedrock mortars and obsidian. Both were imported from outside the area, with obsidian coming from the east and the idea of the bedrock mortar coming from the west. We argue that the presence of transported obsidian, much of it deposited prior to 1000 cal BP, and the later establishment of bedrock mortars encouraged more persistent use of this landscape. We see this as an example of the downstream effects of niche construction.
