Slot Canyon

The ooze of earth and water, rivulets of mud, Moves slowly, then faster, as rain pushes its mass. Both water and earth mix in this massive great flood, As it's trapped and rises in a slot canyon's pass. As it inches up the wall's of Zion's great rocks, It swirls and heaves like the rage of an ogre. The tightening 'V''s, so like a corset, which blocks The rising tide in shades of brown and ocher. The warnings are clear, and the dangers are present, With a message to all, "Avoid the desert slot", Especially when heavy rains are recent. It is surely not where I'd like to be caught.
