Along with Davis Mountain. The lesser roads that got you in closer to the base of Round Top were very muddy. On the drive in they weren't too bad as the ground was still sort of frozen, but in the short hour and a half it took to do the hike they had gotten pretty bad for the drive out.
Started off by doing 6843 from Lookout Pass. Then hit 5862/Davis Knolls. Then headed to the east side of the Davis Mt/Round Top area and parked, as we only have a lowly Subaru. Rode mt bikes to the base of 5865 and climbed it on foot. Went back to our bikes and road them to the base of Round Top where we just laid them on the ground as there wasn't anything to lock them to or hide them behind. First did Davis Mt South (6200), then went over to Davis Mt, and then to Round Top.
Went to Round Top and Davis Mountain. I also had threatening weather on my hike and made it down before the rain came.
A good place to look at the Dugway Proving Grounds and wonder "What the heck is going on in there?"
Following the lead of Eric Willhite's TR that he posted, I also went over and topped out on Davis Mountain. Nice area for a snow free hike at this time of the year. The weather was threatening most of the time I was on the mountain but held off until I was back in my vehicle for the rain.
