Mark is doing well. Climbed in 4:30 round trip from the usual starting place in the wash. Fun hike!

Found it while geocaching at the Castle Dome Summit.

The first time to log a benchmark.
Today my "Entourage" walked up this Hill and found the Cache and the Benchmark.

Got this one after the hike to the top for the virtual cache here.

This benchmark is actually for the peak itself, not the disks that were placed much later than its first use by surveyors. Its horizontal position was determined by viewing it from Signal Peak, Black Butte and Stud Mountain, among others, during the 1910 survey of the Texas-California Arc of Primary Triangulation, the first major triangulation survey done by the USC&GS in Arizona.
