DF 0.28.40d16
found some interesting location here: it has magma pipe, river, underground river, bottomless pit, HFS, aquifer, some trees, sand, obsidian and flux, everything in Terrifying biome, which means a few pages of sceletal naked mole dogs, troglodytes, antmans, fire imps and even a sceletal troll and giant cave swallow. the location is here:
possibly other interesting places in the same worlds as it has a crazy amount of rivers and volcanoes, could be easily tweaked to non-evil settings (i was looking for a world with a waterfall full of zombie carp/hippos next to a magma vent, with no luck so far)
