History

The surrounding area was once inhabited by the Saklans. A Saklan village, which was possibly occupied from 1500 until 1772, is located near the mouth of Tice Creek. It contains multiple bedrock mortars used for processing acorns and other foodstuffs as well as a small spring. Its location along is not far from its confluence with the much larger Las Trampas Creek would have been advantageous to the Saklans who inhabited it. A small plaque marks the site which sits next to the bus stop at Tice Valley Boulevard and Montecillo Drive.
