Brandberg Massif

Brandberg Massif is the highest mountain in Namibia. Because there is a lack of deep soil in this area, different types of rocks are plainly visible on the surface, including granite, schist, and sedimentary rocks.

Meteorites are Vanishing Below the Antarctic Ice
CNN
More than half of the meteorites that have been collected so far have been found in Antarctica. The dark meteorites are easy to see on the snow-white surface. However, the meteorites' dark color also causes them to heat up in the sun, melting the surrounding ice. The meteorites can sink into the surface little by little, until they disappear from view.

No Need to Spray for Cicadas
U.S. Environmental Protection Agency
Trillions of cicadas will be emerging across the United States in a few weeks - but don't panic! The bugs might look creepy, but they cannot bite or sting. They won't eat your flowers or garden produce, and they are for the most part harmless. You may want to protect young trees with netting, but don't use pesticides, as they are harmful to other organisms and will not be effective in keeping cicadas away.

In Peru, there is an initiative underway to help the miners restore part of the rainforest in Madre de Dios. The miners are also taught how to extract gold without the use of toxic mercury, which poisons the soil, water, fish, and the local people.

Cross section of Long Valley Caldera. The resurgent dome, Doe Ridge, Mammoth Mountain, and the Inyo Craters and Domes all reflect volcanic activity since 760,000 years ago, when a giant eruption formed the caldera. The thermal springs in Hot Creek are fed by Sierra Nevada snowmelt that seeps underground and migrates eastward in the vicinity of partially molten rock (magma) beneath the western part of the caldera. The water cools as it migrates eastward beneath the ground (red arrows). Image and caption by USGS.

Additionally, the water level has risen by more than a foot, and now the sidewalks flood twice a day with the tide. Site preparation will begin this May, and the new seawalls are expected to be complete in 2027.
