why would a ice level be in a desert level

Well, in a desert, places that lack sunlight (caverns, for instance) don't necesarily retain scorching heat.
As a matter of fact, they can get pretty darn cold.
Now cold enough to make ice formations and snow...
That's something of fantasy, nothing more.

A desert is a place that there is very minimal precipitation of any kind, such as rain, hail or snow. Deserts, like Dry Canyon are very hot and humid and as a result, have no cold fronts coming in to deliver rainfall. In Ice Cavern, the temperature is too cold for rainfall because it freezes it before it can precipitatie.

Well, in hot places there can be snow, in example Kilimanjaro in Africa, big mountain, around 50 Celsius degrees and on Kilimanjaro there are snow and ice!
