Just to interrupt your #doomscrolling, here are some beautiful photos from Pinnacle Lookout near the QLD border my brother just took. He's getting away from it (ie. being jobless and a renter) for a few weeks and felt really uplifted by just getting out into nature.

Update: We are looking into the Tweed Caldera, over 1000m deep and 40km wide, one of the largest and best preserved #calderas (cauldrons) in the world and has World Heritage listing for its rich diversity of plant life.

The Daily Overview (https://dailyoverview.com) had this fine image of a volcano I'd never seen before, so I swiped the image and a lot of their text.

Tofua is a volcanic island in the Pacific nation of Tonga. Its sides rise steeply to the rim of its caldera, which is partially filled by a deep crater lake. The island is a national park, containing unique bird species and the largest undisturbed Tongan tropical moist forest in Tonga.

While the Yellowstone Caldera gets all the public attention, an older and smaller caldera in New Mexico also has an important story to tell. In fact, the Valles Caldera is where scientists first sorted out the workings of volcanic systems that produce large explosive eruptions that make calderas.
