A 22-million-year-old petrified #mangrove forest found in the Panama Canal https://phys.org/news/2024-01-million-year-petrified-mangrove-forest.html
An early #Miocene (#Aquitanian) mangrove #fossil forest buried by a #volcanic lahar at #BarroColoradoIsland, #Panama https://www.sciencedirect.com/science/article/abs/pii/S0031018223006247
"approximately 1 million years after the formation of #BarroColorado Island, a #volcano erupted, followed by a #lahar, which covered the island with mud and rocks. It also covered the #MangroveForest that had grown around the edges of the island."

When they said, “#PugetSound is built on #Rainier’s mudflows,” I didn’t realize they meant that there was no land where Tacoma, Kent, Auburn, and Renton currently are before the colossal #OsceolaMudflow filled in those parts of Puget Sound 5600 years ago.

Via the U.S. Geological Survey, on Tuesday, a small debris flow was detected by several of Mount Rainier's lahar monitoring stations, likely the result of an outburst of water from the South Tahoma Glacier that grew into a debris flow, which isn't surprising given the current heat wave in WA.

@janinekrippner Turns out this can also happen in lahars! Here's a spot on Mud Creek at Mount Shasta from earlier this year. That ropy thing USED to be a tree branch, as far as I can tell. Now it looks like a piece of kelp! #volcano #mudflow #lahar
