What an awesome picture! That has to be a really neat place!
Kylie, you would love it there... it's an old silver mine which also produced some gold and later the entire mine and town was purchased by Walter Knott of Knott's Berry Farm amusement park fame and the same Knott as Knott's jellies and jams you get in the market. It's now a San Bernardino County Park open to the public and nestled at the southern foot of the Calico Mountains which are rifted with many active faults and fault splays and is on the Eastern California Sheer Zone and was in the path of the 1992 Landers Quake (M7.3) which although didn't rupture that far north its directivity focused the greatest amount of energy in that direction which damaged the ghost town which also experienced many aftershocks for the better part of two decades. There is also great rockhounding in that area as well as geologic oddities and curiosities to explore.
