Above is the fiberglass mountain Prehistoric Forest entrance. Back in 2010 I wrote, "...at least when I visited everything was well maintained and freshly painted," but looking at this photo now I have my doubts. Are those yellow areas on the mountain where the grey paint has pealed away? Although the two-tone color scheme kinda breaks up the monotony of solid grey.
