On a previous ride, "Pony Mine Tour", I arrived at the top of "Windy Pass" and stopped for lunch. Looking at the map, it seemed to indicate that a trail leading to the west of my spot would allow me to exit onto another trail and then onto Boulder Road which I could take south to Mammoth. I used my binoculars to scan below and I could see a house with a small road leading to it. I could not see any road/trail past the house that would lead me up to my current location on top of the mountain. I explored the area looking for any sign of a trail leading down but could not find one even though it was marked on the USGS map. It became extremely steep very quickly and I decided it was not worth the risk to go any further down the side of the mountain on the search for this trail or else it would turn into a potential catastrophe. I decided that I would return from the west, look for the house and see if I could find the trail leading up the mountain to Windy Pass. I reached the house but the trail/road quickly disappeared behind the house and became thickly overgrown and therefore became a dead end. I abandoned this leg of the trip.
