The Grand Canyon: Experiencing the Wonder of the Great Unknown


Sermon for July 31, 2016, by MVUC members Angel Collins and Ed Venzke.

“We have an unknown distance yet to run, an unknown river to explore. What falls there are,
we know not; what rocks beset the channel, we know not; what walls ride over the river, we
know not. Ah, well! we may conjecture many things.”  — John Wesley Powell, Canyons of the Colorado
