About 50 thousand years ago, a nickel iron meteorite about 150 feet in diameter blazed thru the atmosphere at almost 26,000 miles per hour and struck the ground here with the force of 10 to 20 million tons of TNT. The resulting crater is over 700 feet deep and just under a mile across. Many have come here as it is one of the best preserved meteor craters in the world. The cost of admission gets you access to the museum and a guided rim tour. Some call the $20 admission fee steep, but a portion of the proceeds go to science and education. Notice in the selfie we are in winter coats as it is in the low 60s with a 30+ mph wind.
