I did this hike in February of 2015. From the base of the mtn. it took me about 2 hrs. to peak. This is a tough hike, it's like walking up hill in a river bed. 95% of the mtn. is rocks. There is no clear path and very little areas to get out of the rocks.
The hike wore out the bottom of my walking stick. Although it is a nice view, to me it's just not worth it to traverse all the rocks. Coming down isn't any easier. I personally won't do it again.
Spanish Springs Peak is just a giant roadless brown hill. It certainly is worthy of a Summitpost page, albeit it isn't my first choice as a hike. I've only done it once myself. In February 2015 were my directions still consistent? I figure there hasn't been any new development, at least none that would impact access.
