I just caught this trip report. It was amusing to read about the decrepit outhouse at Eureka Sand Dunes. My first visit there was in 1988 with a follow-up in 1990. I'm not sure if it was the first visit, or if in fact the outhouse was built between '88 and '90, but I have memories of it being nearly new, very clean, and an unexpected luxury in that location. I guess that was a while ago ...
