Sat., June 10, 8–10 AM. Join para-botanist Jerry Green and explore the history of the arsenic-gold mine on Black Mountain. Also learn about the native habitats, plants, and animals of Black Mountain. Bring water and sun protection and sturdy hiking shoes. Meet in the parking lot at the north staging area. The entrance is off Carmel Valley Rd., on the south side of the road, about 1⁄2 mile east of its intersection with Black Mtn. Rd., Rancho Peñasquitos 92129. If you hit Valle del Sur Ct., you’ve gone a hundred yards too far east! Do a u-turn and come back around.
