As the name suggests, Caldera was made to be similar in appearance to a real-life volcanic caldera. Other than this, the map is fairly simple, featuring a large palm tree forest on the caldera's outer rim, a small waterfall, and an unfinished river. The map also features a small cave filled to the brim with comfort crystals. See if you can find it!
Like any other map in the game, Caldera features a tidal system. Compared to Ancestral Plains, though, Caldera's tides are far from extreme. It is hard to notice the tides on this map, since most player activity is centered far from the shore.
