Seaman Wash Dispersed

So this is a very, very long, box bladed, very smooth dirt road. On either side it looks as if a snow plow has come through and just piled up the dirt. In some places over 2’ high. Near the entrance, there are various places where folks have pulled off into the sand and parked/camped. However, the areas are small and still very bumpy & sandy. There are a few places where it looks like off roaders come for fun, but with all the very prickly underbrush, it’s not very “camping” friendly. The road is VERY long, and I was driving a 2WD van, towing a utility trailer. I turned down the road to scout out a place for us to park our 5th wheel for the night. Eventually the small camping spots disappeared and all there was were walls of dirt on either side with no where to turn around in site. Judging from the map the dirt road went on for a few more miles. I decided not to go any farther as there was zero cell service and my phone went into satellite SOS mode. I’m so thankful I did not get stuck trying to turn around, that would have been a very long walk in the dark back to the main road. I will say that it is very remote, and the road is wide and flat and smooth enough to just park on for the night if you don’t require a camping spot, but DO NOT attempt to pull a trailer in here unless you feel like during all the way to the end to turn around, or want to back allllll the way out. I finally stopped to turn around about 2 miles in, at the cattle guard. I very nearly got stuck in the very soft dirt. I have no idea
