Down here, mountains/mountain ranges are called "Sky Islands" (so... Islix). This is a section of the Pineleño range in southeast Arizona. Every biom from alpine to desert can be experienced hiking from top to bottom. They produce a lot of precipitation which races down into the valleys and that's when the infamous flash floods happen. Although, being the desert, they are usually dry and if you're hiking, you're most likely hiking in an arroyo.
