Griffith Peak is a great 1/2 hike-trail run to the summit and back on a hot summer day. Its not far from LAs Vegas and you can get some pretty amazing views from the top.   There is a 10.2 and 3,500 ft gain out and back trail that takes you right to the peak. 

I went to check out this peak to search for Griffith peak Pit which is a cave somewhere on this mountain.  Unfortunately, I was not able to locate this cave but I think I am close.  

There is some great camping places at the upper ridge of this peak which is great practice for larger mountain trips in the area.   This peak sits right at 11,000 ft and change.
