  • A colorful rainbow glows above a dirt road near Hunt Mountain in the Bighorns.
    Hunt Mountain Rainbow
  • During a heat wave I always like heading up to the Bighorn Mountains to cool down. I kept driving until I could go no higher. This highway, (14A) was opened for the season at the end of May and many snow drifts still remained. Darkness arrives very slowly this time of year, so I made some coffee and waited. After 11PM the blues of twilight finally faded away. Nights like this are rare at this elevation. No cold, wind, clouds, haze or anything else spoiled the view. It was perfect for stargazing. No matter how many times I see it, I'm always blown away by the sight of the milky way rising in a dark sky. Glittering star clusters, clouds of dust both dark and bright, glowing nebulae of all colors filled the scene. The more you look the more you see. A star tracking mount was used to counteract earth's rotation, allowing me to capture this highly-detailed image.
    Hunt Mountain Milky Way
  • A bright Perseid meteor burns up in the earth's atmosphere while the milky way stands on end in the west. After finding the nearby campground full, I drove a dirt road up to 10,000 feet until I found a spot flat enough to camp. With no trees up here, there was a great view of the sky and the lights below are from the town of Greybull. Over the 2 nights of the Perseid meteor shower in mid-August I captured nearly 1,000 images with about 10% of them containing meteors. This one was the brightest and the longest, spanning over 15 degrees of sky. I nearly missed it because it was the very first frame of my time lapse. Perseid meteors are made up of small pieces of comet debris that cross the Earth's orbit every year. It is the extreme speed at which it enters the atmosphere (over 100,000 mph) that causes the debris to vaporize and glow. The color of the trail reveals the chemical composition. The green is nickel or magnesium, and the red is ionized oxygen or nitrogen in the upper atmosphere.
    The Longest Streak
  • Hunting for the aurora from the mid-latitudes can be a frustrating endeavor. For every night that I've clearly seen the northern lights, there are 2 more where I've gone out only to see the aurora quickly fade or clouds overtake the sky. But perfect nights like this one make it all worth it. After NOAA issued a geomagnetic storm warning, I headed for the Bighorn Mountains. The aurora was obvious as soon as I stepped out of my car. But it was just a green glow without any structure or movement. At 12:30AM, the lights began to grow brighter. Pillars topped with purple and red suddenly rose up and moved rapidly back and forth. This is called a substorm. Charged particles in the solar wind causes pressure to build up against Earth's magnetic field. The magnetic field will suddenly 'snap' and the release of energy makes the aurora intensify. Substorms are unpredictable and often last only minutes. In this frame I caught a Lyrid meteor burning up above Steamboat Point.
