Can anyone “Spot the Rock” this week? This photo shows one of the many textures present in Utah’s geology. Tell us where you think this is!

UPDATE: Location Revealed
The Honeycombs, or Honeycomb Hills, is a solitary cluster of hills far out in Utah’s West Desert between the Fish Springs and Deep Creek Ranges. The hills are a product of a violent volcanic eruption some 4.7 million years ago, where forty feet of tuff underlies a 200 million cubic yard dome of topaz-rich rhyolite. The Honeycombs gets its name from the texture of the rock; a recurrent pattern of alcoves, hollows and cubbies, called tafoni, created from a weathering process known as honeycomb, cavernous, or alveolar weathering. This type of weathering is most common to seacoasts and deserts in sandstones and granites on inclined or vertical rock faces. Salt weathering has been implicated in forming tafoni, as well as many other physical, chemical, and biological mechanisms. The weathering of rock into tafoni can occur rapidly, as seen on seawalls built only centuries ago.

Goblin Valley State Park • This iconic park and its hundreds of aptly-named rock formations probably didn’t need the kind of worldwide publicity it received after Glenn Tuck Taylor toppled one of its goblins last October.

Quartzite of the 900 million-year-old Big Cottonwood Formation holds up the rugged headwall of Mary Ellen Gulch. Well-preserved ripple marks and mud cracks indicate the Big Cottonwood Formation was deposited in the tidal zone of a shallow sea.

Towering cliffs of Jurassic-age sandstone constrict lower Zion Canyon. The prominently cross-bedded Navajo Sandstone, deposited in a vast dune field comparable to that of the modern-day Sahara, forms the cliffs, including the narrow spine of Angels Landing at left.

Happy Memorial Day!

Great Salt Lake occupies a large basin formed by horizontal stretching of the Earth’s crust across the region. This stretching produces movement on faults, resulting in uplift of mountain ranges adjacent to the
basins and occasional magnitude 6.5–7.5 earthquakes.

Jeanette Bonnell likes to play in the dirt. The 62-year-old retired human resources specialist is also pretty handy with a dentist’s drill.


The unique landscape of Southern Utah offers endless opportunities for depiction as well as discussion, and its geological formations have provided countless artists with creative inspiration.


Here’s a photo to help you get back into the swing of things. We hope everyone had a great weekend!

We’ve got some great #tbt photos from the Library of Congress this week. From their vast collection of historic Utah photos, we’ve picked out a couple that really take you back.
