Archeological evidence from missions in northern California conclude that Native Americans rerouted obsidian exchange networks through Spanish missions such as [[Mission San José (California)|Mission San José]] which existed from 1797 into the 1840s. Mission San José was located in [[Ohlone]] territory, where stone tool technologies were prevalent. Despite the constraints of colonialism, Native Americans who lived at the mission were able to trade obsidian through direct geological sources such as the Cascade Range in modern-day northern California and Oregon or through evolving trade networks, which involved interactions with other tribes, as well as the Spaniards.<ref>{{cite journal|last=Panich|first=Lee M.|date=June 2018|title=Native acquisition of obsidian in colonial-era central California: Implications from Mission San José|url=https://www.sciencedirect.com/science/article/pii/S0278416517301629|journal=Journal of Anthropological Archaeology|volume=50|pages=1–11|doi=10.1016/j.jaa.2018.02.002}}</ref>
