Drunk on Geomorphology - Waterpocket Distillery

The next Drunk on Geology is for the Waterpocket Distillery out of Salt Lake City, UT. 

Before leaving Utah I made it a mission to visit the Waterpocket Distillery because there are few alcohols that more encompass the geology than this one. The distillery is named after the characteristic fold in the rocks that encompasses Capitol Reef National Park. According to the distillery's website:
The Waterpocket Fold gives form to the Capitol Reef and the national park that bears this name, and now gives its name to Waterpocket® Distillery.

Not only is the Waterpocket Distillery named after a geological feature, they also have geologically themed alcohols within their collection including the Temple of the Moon Gin, the image on the Waterpocket Cocoa & Rum, and the Toadstool Notom Amaro No. 1.

The most characteristic features of Capitol Reef is the way that the rocks have been folded across the park. With an axis running nearly 100 miles north to south, is a feature called the Waterpocket Fold. There are several different types of folds when we look at rocks. When rocks are folded in a "U" shape, this is called an syncline. When rocks are folded the opposite way, essentially an "A" shape, this is called an anticline. However, when you have a stair-step fold, where one side of the fold is generally horizonal, then its comes down to another horizonal layer, you have what is called a monocline, and that is what the Waterpocket Fold is. You can essentially see this fold in the way that the rocks dip towards the east through much of the park, such as in the image above looking towards the south.

Looking west off the Cohab Canyon Overlook  you can see the dip of the beds towards the east as well as most of the rock units we talked about.

As you can see in the profile above of the Waterpocket Fold, there are several rock formations that make up the rocks in Capitol Reef NP. Folded approximately 50 to 70 million years ago, the rocks within the park mainly range in age from the Early Permian age White Rim Sandstone (~280 million years old) to the Late Jurassic Age Morrison Formation (~150 million years old). Because of the Waterpocket Fold, the older rocks are easier to see in the western portion of the park and the younger rocks are more exposed in the eastern portion of the park. 

Let us focus in on the liquors from the Waterpocket Distillery. In the north part of Capitol Reef National Park is Cathedral Valley, where you can find the Temple of the Moon. The Temple of the Moon is pictured on both The Temple of the Moon Gin, from which the gin was named, and a more stylized version on the Waterpocket Cocoa & Rum. 

The text on the back of the Waterpocket Cocoa & Rum
We take our turbinado sugar & blackstrap molasses rum (fermented & distilled in-house, then aged in used whiskey barrels), and combine it with fermented and sun-dried Caribbean cocoa custom-roasted at the distillery. Open Wild for a decadent rum sipping experience, rich in cacao, spice, and rum flavor. 
The text on the back of the Temple of the Moon Gin
We dedicate this gin to the sacred Temple of the Moon in Capitol Reef's Cathedral Valley. Inspired by the juniper and pinion forests of Utah's high desert country, we crafted a gin of uncompromising artistry and beauty. Made with: Coriander, Lemon Peel, Lavender, Angelica, Ginger, and 10 other botanicals.

The monoliths of the Temples of the Sun (in the background) and Moon (foreground) are composed of the Entrada Sandstone. Looking at the cross section above, the Entrada sandstone is exposed along the eastern portions of the park and is one of the youngest rocks exposed in the park. The Entrada Sandstone is a buff-pink colored sandstone deposited during the Jurassic age (~150 million years old), formed from a coastal dune environment. The Entrada Sandstone is the same formation that is more well known as the rock that the arches are comprised of in Arches National Park, located to the east of Capitol Reef National Park.

The cement in the Entrada Sandstone is one of the key ingredients. Many sandstones are cemented by silica, which is basically a dissolved type of quartz, a very hard mineral. Those types of sandstones are incredibly difficult to erode. The Entrada Sandstone, however, is cemented with calcite, a mineral that easily dissolves in slightly acidic water, such as the calcite in caves. This means that it crumbles fairly easily and is removed rapidly by flowing water. 

Capping the Entrada Sandstone in these parts is the Curtis Sandstone. A grayish-green sandstone and siltstone that is more more resistant to erosion than the Entrada and protects the monoliths from complete erosion. 

The last bottle pictured above is the Toadstool Notom Amaro No. 1. From the Waterpocket Distillery's website:
Like the toadstools of Escalante's Grand Staircase, the great artistry of these liqueurs and bitters is the delicate balancing act of bitterness, aromatics, and other natural flavors. A warming of the throat and stomach highlights the traditional consumption of this type of spirit as a digestive or digestif, or after-dinner liqueur. We think this also make them perfect for after-ski, after-hike, or as an intense flask-filler for your next adventure into the wilderness.

The Toadstool is named after geological features not in Capitol Reef this time but those a little further to the south in the Grand Staircase-Escalante National Monument. These features are known as the Toadstool Hoodoos. Hoodoos are:
 A column, pinnacle, or pillar of rock produced in a region of sporadic heavy rainfall by differential weathering or erosion of horizontal strata, facilitated by joints and by layers of varying hardness, and occurring in varied and often eccentric or grotesque forms. (Dictionary of Geological Terms, 3rd Ed.)

Even though these toadstools are much further south than the Temple of the Moon, these are also formed from the Entrada Sandstone, however here instead of being capped by the Curtis Sandstone, they are capped by the Dakota Sandstone. As the Entrada Sandstone erodes away, the much more resistant Dakota Sandstone protects the smaller column in the middle, much like the Temples of the Moon and the Sun. 

The Dakota Sandstone is Early Cretaceous in age, ~100 million years old, and represents the western shore of the very large Cretaceous Interior Seaway. The Dakota is made up of yellow to grey sandstones, mudstones, and a few thin beds of coal. These were deposited within a wide range of coastal environments including deltas, alluvial fans, and coastal deposits.

Drunk on Volcanology - Lava Lake Wit


The next Drunk on Geology is for Lava Lake Wit from the Crazy Mountain Brewing Company, out of Denver, CO. 

To start off, a "lava lake" is just what it sounds like, a lake of lava, or to be more technical per the NPS:
A lava lake is a pool of molten lava that persists in a vent or crater of a volcano...
Of which the only lava lake in the United States is found on the Big Island of Hawaii in the caldera of Mount Kilauea.

Lava lakes, at over 2300 degrees Fahrenheit, are not very common across the planet at all, for obvious reasons. There must be a specific set of circumstances to maintain that liquid lava and not to eventually cool down forming igneous rocks. The lakes are maintained by the stream of volcanic gasses including sulfur within the caldera of the volcano that prevents the lava from cooling enough to solidify. 

Although the lava lakes are essentially "permanent" they do frequently drain and refill depending on the plumbing going on beneath the surface of the volcano as earthquakes and other forces redistribute the magma paths.

There are currently eight known lava lakes on Earth. Besides Mount Kilauea in Hawai'i, there are lava lakes in Ethiopia (Erte Ale), Antarctica (Mount Erebus), Vanuatu (Mount Yasure and Ambrym) and Nicaragua (Mount Masaya), with the largest known lava lake located in Congo (Mount Nyiragongo) measuring 820 feet in diameter and up to 2000 feet deep.

Looking at the back of the can, it says:
Slow down and take in the scenery with Byamba, one of the brighter creatures on Crazy Mountain. She boils the water for brewing with a zest for life that is contagious. Her personality is lively, refreshing and a little complicated. So pause for a moment and join her for an afternoon amid the blooming chamomile on Lava Lake. 

The text on the can made me wonder if that indeed we weren't only referring to a lava lake, as in a boiling lake of lava, but an actual place called Lava Lake. And it turns out that there is indeed a lake located kind of near Vail, CO called Lava Lake in White River National Forest. 

Lava Lake, CO

Which looks just like a cute little mountain lake on Lava Creek, although I'd prefer to take an afternoon next to an actual lava lake.
