Thanks!! It is not like the rivers and streams run in an underground tunnel, it just flows through the loose alluvial fill that fills the bottoms of the canyons.

Kind of like a trough half full of sand and a few gallons of water thrown in. Most of the sand is still dry, but the water can move underneath without disturbing the sand up top. When the canyon walls come together it is like the trough is narrowing forcing the water on the bottom up to the top of the sand until it gets past the point of the narrowing and goes back down to the bottom.
