South of Pudding stone...To Vee and Gary re: Pomona.<br />South of Pudding stone reservoir (aka Frank G. Bonelli regional park) is Elephant Hill. A volcano located just east of the I-57 by the railroad tracks. W.Mission road cuts right through the center of it, you can see the cone shape from inside of the volcano as Mission turns into Diamond Bar. Gypsum can be found in the road cut. This is the epicenter that cause the pudding stone to rise and create the hills and formation to the north of the I-10. Info came from Geology class 1977.

East of Linder Equestrian Park in the Glendora Hills is another exposure.
