Please generate a detailed description of a narrow passage with a steep incline and a thick layer of loose rock and mud covering the floor.

This narrow passage inclines steeply, making footing precarious. A thick layer of loose rock and mud covering the floor compounds the problem, but with care and balance it is possible to move onwards. Needle-like sprays of white crystal radiate from the walls and ceiling, adding a further impediment to travel.
