Produce a detailed written description of a glistening cave in the wilderness with icicles and a partially obstructed opening in the ceiling.

Shifting beams of light filter through a partially obstructed opening that splits the pinnacle of the ceiling, causing the surrounding walls to glisten like a freshly cut diamond. Snow-dusted icicles hang between rough patches of stone that protrude from the foot of the gap, stretching down the faceted walls to just above the floor.
