Rick, looks like the pictures you posted were taken late in the day on Monday. When I went up the Bowen Ranch Rd past the cattle gaurd there were no tracks heading up that way since the snow of the previous night. When I came back down the Bowen Ranch Rd around 2PM past the cattle gaurd the tracks I made were still snow. The sun came out a bit later which must have melted the compacted snow down to the mud. Also on my way out I noticed a number of groups of people with cars up in the area to play in the snow. It looks like some folks went up past the cattle gaurd after I had been through. When I attempted to go up the Bowen Ranch Rd I made it about a third of the way up the steep hill just south of Luna Vista Rd. I could see that to attempt to get up any further would have been fruitless, finding me sliding off the road into the ditch on the left side.
