2021 Map of Las Trampas Ridge
USGS Topo · Published 2021About this map
Lafayette and Walnut Creek anchor the northern reaches of this topographic study, where suburban expansion meets the sharp relief of the Diablo Range. The landscape is dominated by the massive northwest-southeast spine of Las Trampas Ridge and Rocky Ridge, creating a natural barrier between the developed corridors of the Stone Valley and the secluded Bollinger Canyon. These ridges are crisscrossed by a complex network of paths, including the Las Trampas Ridge Trail - North Trl and the Madrone Trl, reflecting the area's transition into protected open space.
