Thousands of years ago, the Siachen Glacier didn't just sit in its valley; it advanced so far down to Tirit that it choked the river. The proof? Deep clay bands left behind by a massive, transient paleolake.

Looks like a dusty afternoon is in store for El Paso, Texas today. A long dust plume coming out of Mexico is aimed right at El Paso. Dust originating from as far upwind as the Janos, Chihuahua, area, as well as Ascension and Paleolake Palomas. #txwx

Some sort of threshold must have been exceeded at about 0000Z UTC, because blowing dust began to be visible on GOES satellite in the Chihuahuan Desert then, from White Sands and the Paleolake Palomas basin. Not a heavy dust event by any means, and looks like it will miss El Paso. #nmwx #txwx

A vanished Holocene lake once covered Central Iran, a region now defined by deserts.
Lake level fell not in one collapse, but through climate-driven pulses of expansion and contraction.

NASA's Techno-Wizardry Grants The Perseverance Rover Greater Autonomy
When the Perseverance rover was sent to Mars, it was largely dedicated to astrobiology. It's driving around an ancient paleolake, Jezero Crater, looking for evidence of past life. But the rover mission is also a testbed for greater autonomous operations. Now, NASA has given the inquisitive rover a way to better navigate the Martian surface with less human intervention.

Not as windy in El Paso as yesterday, but sufficient enough to be raising dust this afternoon from Paleolake Palomas in Mexico. It looks like this dust will miss El Paso, due to more WNW trajectories, perhaps impacting Hudspeth County eventually. #txwx

Gobi Desert had water, vegetation, and human camps just 8,000 years ago
Evidence from the Luulityn Toirom paleolake shows the Gobi Desert in Mongolia supported human life about 8,000 years ago. It matters because it connects climate swings, lake growth and collapse, and everyday toolmaking to survival in an extreme landscape. Sediment layers near this dried lake in Mongolia preserved a wet history that the paleolake study

3/ At 300 km southeast of Amman, in the Khashabiyeh paleolake, a Franco-Jordanian team discovered eight kites forming a 17 km chain. Excavations (2013-2021) revealed charcoal dated to 7000 BCE (Pre-Pottery Neolithic B period).
