As part of their on-going effort the Sierra Club took on Buchanan Canyon

University Heights’ Buchanan Canyon is a famous archeological site, whereGeorge Carter started working in the 1940s and found pebble tools, evidence that people may have been on this continent longer than the 13,000 year date that most archeologists accept. The sediments of Buchanan Canyon span the time from the most recent (Holocene), through the ice age (Pleistocene), to the Eocene (42 million years ago). The Friends of Buchanan Canyon have been restoring the native habitats here for a few years, removing the invasive arundo donax and planting natives in their place. Yesterday the San Diego Sierra Clublended their volunteer efforts to this beautiful urban treasure. Sunday they’ll be working on the 32nd Street canyon in Golden Hill. If you would like to join them for today’s habitat restoration event — from C Street walk to the end of the 32nd Street dirt road, past the gate, for about three blocks, look downhill to see the restoration party. Bring gloves, shovels, trowels, hat, sunscreen, snacks, water…and a hole-digger or wheelbarrow, if you have them. Questions? Call Tershia at (619) 239-6120.
