Here are some of the pictures I took at National Parks that I visited between 1987 and 2006. I have visited both the Grand Canyon National Park and Yosemite National Park several times. I made one visit to Yellowstone National Park and Arches National Park in the summer of 2000. Some of the older pictures are scanned from color slides using a Nikon Coolscan IV and some are digital images taken with a Nikon D100.

Awesome pictures, I have been to Yosemite and Yellowstone with Grand Teton, Colorado Rocky, but missing those nice parks in Nevada, Arizona. These are in my bucket list now.
Thank you, Kaz, for your comments.
