According to Wikipedia there are 59 National Parks and 109 National Monuments. We have been to 32 of the National Parks and 16 of the National Monuments. I guess that may be considered impressive and that does not include National Recreational Areas. Most of the National Monuments I have never heard of, including the Kasha-Katuwe Tent Rocks National Monument, which is 55 miles northeast of Albuquerque. A friend of mine knew of it and suggested we hike there.
This area was named a national monument in 2001 and includes 4,645 acres of public land. The words kasha-katuwe mean white rocks. Rocks found here were formed 7 million years ago when 20 small volcanoes erupted repeatedly. The tent shapes were caused by erosion from wind and water.
They have two trails there, the slot canyon trail and the cave loop trail. Together they are just over three miles. All of the hike was scenic, with views of desert flora, cliffs and the tent rock formations. Hiking through a slot canyon is always interesting with its twists and turns. There was a steep incline after the slot canyon that led to outstanding views. If you find yourself in this area, I highly recommend this hike.
