Check out the Angeles Lower Peaks Committee
The Lower Peaks Committee and LPC list have been around for some time, since the 1990s. It was the effort of several Hundred Peaks hikers some of who lived in Orange County. They liked to hike the peaks in the Santa Ana Mountains most of which were not on the Hundred Peaks list (which listed peaks 5,000’ or higher). So, they got together and began to compile a list of peaks under 5,000’.
