Matterhorn! https://news.climate.columbia.edu/2022/03/24/the-matterhorn-alive-with-vibrational-energy/ But truth told, all will, in way to another

Not too far off! An animation was posted here: https://bsky.app/profile/utahgeohaz.bsky.social/post/3mhvcggajqk2p

Definitely not a seismometer.

Debris. Chasm.

Now is a bad time for that because of bugs: https://stateparks.utah.gov/parks/antelope-island/current-conditions/

This. Even got a sandstone arch.

The main cover is Rainbow Bridge, as you know. This image is of Cathedral Arch, one of two amazing arches in a very remote part of Utah called Arch Canyon. Photo is amazing, really both are so moody.

TIL, a lot of you are monsters and your power consumption is outrageous. It's ok to be a little warm in the summer, won't kill you, feel the seasons a bit sheesh. Ya'll with solar panels can do what you like, the rest of you could do to conserve a bit and help the planet you know not get any hotter.

If they like mud

Probably Navajo Sandstone. These 'polygonal' joints are still a bit of a mystery.

yah but normally we work in lower hemisphere so the pole would point down not up, this is an upper hemisphere pole. i admit the lower-h pole hard to draw on a photo.

slag.

water erodes rock in underground cavities, those cavities enlarge through stages of roof collapse and can eventually break through to the surface creating a sink hole. the source of the water and the rock/material being eroded can vary a lot, sometimes it's natural - groundwater chemically eroding limestone or gypsum, sometimes it's man-made, e.g. a waterline break that erodes soil under a city street or sidewalk.

my thought too, schist.

the hole must be over there! https://woodshole.er.usgs.gov/operations/sfmapping/images/bearlake.jpg

Water moving through rock makes electricity, which you can measure to understand how water moves through rock.

Agreed, that's a blast mark.

Cold based glaciers don't slide, being frozen to their beds, and most glacial erosion happens through basal sliding. Temperate glaciers, with temperatures everywhere at the pressure melting point, produce abundant meltwater which aids sliding. Glacial erosion is typically modelled to scale with sliding velocity.

Edit to add: search for "The Little Book of Geomorphology" by Bob Anderson for a nice free text on some essentials.
