Colorado is probably my favorite state. My mom and dad took my sister and I on numerous vacations to and through Colorado in my early years. I always looked forward to the first glimpse of the snow-capped mountains. Once I had a family of my own, Colorado continued to be a focal point of every trip toward the western United States. My wife, Kathy, also grew up frequently traveling to Colorado with her family. As a result, we were married just outside Estes Park, Colorado, with the Rocky Mountains in our wedding pictures. Now in retirement, we go to Colorado every year and try to see places we have never seen before.

Near Colorado Springs, this is Garden of the Gods in the foreground and Pike's Peak in the background. Photo was shot with a polarizing filter to bring out color. (2010)

Early morning at Garden of the Gods. (2010)

This is a portion of Garden of the Gods shot in the morning with an infrared camera. Infrared cuts through haze in the atmosphere, so the scenery is sharp, even in the distance. (2016)

Looking at the bridge over the Royal Gorge. The Royal Gorge is 1,250 feet deep. (2010)

In 2003, I and a friend spent a week at Meyer-Womble Observatory to make observations of Mars and several comets. This is Echo Lake on the road to the observatory. Photo taken with a polarizing filter. Altitude close to 11,000 feet. (2003)

This is Meyer-Womble Observatory, which sits near the top of 14,271-foot Mount Evans. The telescope is dual aperture, meaning it is a binocular telescope, with each telescope being 28.5-inches across. (2003)

As we were driving to Aspen, we reached Independence Pass on the Continental Divide on July 1, 2010. The elevation was 12,095 feet. Although a beautiful sight, it was very windy and cold. Luckily we had brought heavy jackets. (2010)

A short distance from Aspen is a group of mountains called the Maroon Bells. (2010)
