Here's a long shot: a big orphan pebble collection from the USGS, yours if you can take and treasure it. See alt text
California Conglomerate Clast Collection Seeks New Home Conglomerate clasts were collected from 279 sites by Vic Seiders and Brett Cox for their report, "Place of Origin of the Salinian Block, California, as Based on Clast Compositions of Upper Cretaceous and Lower Tertiary Conglomerates," USGS Professional Paper 1526 (https://pubs.usgs.gov/pp/1526/report.pdf). This is an extremely important comprehensive collection. Localities are principally in or near the Salinian Block in western California, but cover from Anchor Bay (Stewarts Point quad, 4,281,400N, 462.390E) to Cabo Vizcaino in Baja California, including a bit of western Arizona. At least one locality, on Highway 92 near Pilarcitos Creek (site WO-268, Woodside quad, 4,149,080N, 555.710E), is now inaccessible, having been encased in Caltrans concrete. In the mid 1990s, when the USGS closed their rock storage depository in Menlo Park, throwing irreplaceable collections in the trash, the Seiders and Cox collection was given by Brett Cox to Kathleen Burnham for safe keeping. However, she used only one of these clasts in her own work, has no further need of them, and has run out of room to store them. The collection is entirely pebbles, size range 0.4-6.0 cm, mainly 0.4-3.0 cm, and samples were etched overnight in 5% hydrofluoric acid solution, to aid in identification. The rocks are neatly stored in boxes measuring 12" x 9.5" x 5". At present the stack is 6 by 3 by 6 boxes, which comes to 108 boxes, and the stack measures 69" x 39" x 30", roughly 47 cubic feet. The boxes are marked and numbered. One box was partially damaged, however, no clasts or markings on the box were lost. Kathleen used the Seiders and Cox locations for some of her own collection, and reports that despite their work pre-dating GPS, their sample locations are extremely accurately specified in their publication. If this collection would be useful to you, and/or you can give these rocks a home, DM me and I’ll pass on your name. clean etched pebbles from the collection Boxes of the collection, each one clearly marked and annotated

Earth's crust is like the very thin shell on an egg - now and then it cracks open, and lets out some more internal heat. Heat from the sun does warm the very surface of the Earth, and is important for example in places that are usually covered in snow, ice or permafrost; and the ocean surface.

An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.
