Hiked it from the trailhead of left fork trail in maple canyon, up to forest road 069 and then to the hill. I actually wasnt positive if I was on the hill or not at the time of summit as I had no way of checking my location, and no map, but looking at a map and some google earth, I'm certain it was a summit. It flattens out on top and is very grassy, I like it a lot. Sidenote: the photos displayed for marble hill on the page uploaded by brandonlovell is not from the summit of marble hill
