Black Hill, Santa Rosa Island

From Islapedia

Black Hill, Santa Rosa Island is a survey station first established by William E. Greenwell in 1860, and revisited by Stehman Forney in 1872. Greenwell recorded:

“Looking about southwest from the anchorage is a very conspicuous black mountain, known upon the island by that name. Upon one of the foothills of this mountain the signal stands. It is in full view of the anchorage. It can be found by following up the cañada leading from the house to its head, thence ascending the ridge to the left.”

Today this station, located to the north of the Black Mountain station, is not marked on topographic maps. [UTM 10: North 3,765,386 East 770,175; UTM 11: North 3,765,792 East 215,955].
