The topography of California has always fascinated me, specifically the deserts (mostly the Mojave) of the east. Originally, I believed the Eureka Valley wasn't part of Death Valley, but was pleasantly suprised to learn it's simply an isolated park of the park. (1/2)

Unexpected things can happen when #glaciers melt. Sure, sometimes they disappear, but other times they can become buried by rocks that protect the ice from further melting. This is one way to make a rock glacier, and could be a future scenario for many #mountain glaciers. I'm happy to be part of a new #openaccess paper presenting a model for this transition, based on observations from the beautiful rock glacier on Mt. Timpanogos in #utah.

As part of my project, I challenged myself to spot natural areas beyond the mainland United States, and even beyond Hawai'i and focused on various overseas territories of the country. One of those I spotted were the Northern Mariana Islands, and spotted the Northern and Southern Pagan Volcanoes.
These are two stratovolcanoes connected by a narrow isthmus. Both volcanoes are exposed calderas due to previous eruptions, which are caused by the subduction of the Pacific plate under the Mariana and Philippine plates.

Much like Hawaii Volcanoes National Park, this would-be national park would protect active lava flows (evident by North Pagan's basalt fields) and various endemic life like the Mariana fruit bat, the Myzomela rubratra ssp. asuncionis, and so on. Further, today, the island is semi-inhabited by a non-permanent population of Carolinian and Chamorro people.

One of the main environmental issues facing this remote area include invasive species such as cattle, Sambar deer, goats, pigs, Antigonon leptopus (love vines), Spathodea campanulata (African Tulip trees), and plans by the United States Navy to transform the island into a Range and Testing area under the belief it's permanently uninhabited.

Good morning from Minneapolis where we've a rather dreich start to the weekend but where we can use the rain.

Quite early Friday morning it's 33℉; overcast skies; light north-northeast winds; and visibility 10 miles at the airport.

- Another messy early spring system today into tomorrow with rain, snow, sleet, and freezing rain expected across Minnesota and Wisconsin.

- Elevated thunderstorms will be possible across southern Minnesota with some isolated hail storms possible.

The abandoned falls, formed at the end of the last Ice Age, is a glen adjacent to Minnehaha Falls in Minneapolis, not far from Wabun Picnic Grounds and the Minnesota Veterans' Home.

"The cataract in the Mississippi has migrated to St. Anthony Falls and Minnehaha has retreated from the abandoned channel to its present location, where the undercutting action responsible for the migration is apparent."

What will this area look like in the next five thousand years?
