Have meteorites or meteorite craters been found in Utah?

Utah Meteorites

Seventeen Utah meteorites (1 fall and 16 finds) are officially recorded in London’s Natural History Museum Catalogue of Meteorites. Based on this "Catalogue" published in 2000, meteorite numbers in neighboring states range from 69 in Colorado to 12 in Nevada, and from 35 in Arizona to 12 in Wyoming. Unfortunately, it is most likely that there are meteorite finds made in Utah that are still going unreported. It is a given that there are meteorite falls occuring in Utah that are going "unwitnessed".

Utah’s meteorites are of the stony and iron variety.

Stony meteorites are the most diverse group of meteorites. The chondritic stony meteorites come from a parent body of primordial material that, unlike the Earth, did not differentiate into layers such as a core, mantle, and crust. Their ages range from billions of years to 170 million years.
The achondritic stony meteorites come from the crust of differentiated parent bodies.

Iron meteorites are the most familiar meteorites. They are heavy because they are mainly iron-nickel alloy, they do not [sic] weather very fast(?), they do not easily fragment when they fall, and they are magnetic. Iron meteorites come from the core of differentiated bodies. Six iron meteorites have been found in Utah. The Drum Mountains iron is the eighth heaviest (529 kg, 1164 lbs) iron meteorite in the U.S., and was found near Delta, Utah.

Impact (meteorite) craters in Utah and nearby states.

Meteorite Craters

The Geological Survey of Canada Impact Database lists four meteorite craters in Utah and nearby states. They are

  1. the controversial (most think it is a salt dome) Upheaval Dome in Canyonlands National Park, Utah,
  2. Beaverhead Crater, Montana,
  3. Barringer Crater (Canyon Diablo, Meteor Crater), Arizona, and
  4. Cloud Creek Crater, Wyoming (known only from drilling records).
