I husband and I drove the southern route along the Mexican border on a return trip from Tuscon. As we drove up through Texas on New Years Day, we came across Palo Duro Canyon and decided to have a look.
The Prairie Dog Town Fork of the Red River eroded Palo Duro Canyon, the second largest in the U.S. The river meanders along the level Llano Estacado in the Texas Panhandle before diving through the Caprock Escarpment into the canyon.
Water, pushing sediment downstream deepens the canyon; wind and water widen it. It is 120 miles long, 6-20 miles wide, and 600-800 feet deep. At each place the river crossed the road through the park, I decided to make a photograph.
The Prairie Dog Town Fork did its river thing as it meandered through the canyon: it shaved mud off its concave bend and deposited it on its convex bend. Sometimes mud piled up on an obstruction in its channel and created a side channel.
I went to Palo Duro before the State built bridges over the river in 2014. Hence, I had direct access to the mud flats, dangerous during the rainy season when the river floods.
