I have been digging out my old copies of John McPhee's #books, dipping in, remembering what it was like to be a new #geologist, and how it has carried across into #spatial #data, #geomorphology, #geomorphometry, #hydrology, #landcover, #engineeringgeology, #environmentalscience, #landuse, #massmovement and so much more......
This one paragraph reminded me so strongly of that time,, although I cannot of course write as eloquently:
--
"I used to sit in class and listen to the terms come floating down the room like paper airplanes. Geology was called a descriptive science, and with its pitted outwash plains and drowned rivers, its hanging tributaries and starved coastlines, it was nothing if not descriptive. It was a fountain of metaphor—of isostatic adjustments and degraded channels, of angular unconformities and shifting divides, of rootless mountains and bitter lakes..."

'Some (TopoBathy) Floodplain Images I Made A Few Years Ago, On The Mississippi R.
--
These are some (topobathy) floodplain images I made a few years ago for a specific usecase – and ‘stumbled’ across them again today, lookin’ for something else…
Every time I look at such things, the (engineering) geologist, geomorphologist, (pseudo) hydrologist, spatial data scientist in me is made happy in being reminded what access we have to (often open) spatial data and the sheer volume of it, and the use cases for which it can be leveraged.
We are lucky professionals…

Map of the United States and Puerto Rico (with state abbreviations shown) comparing percentage of landslide susceptible terrain from the N10 model to density of mapped landslides from the national inventory compilation (Belair et al., 2022) for each U.S. county.
Map of landslide susceptibility (∼90-m) for (a) conterminous United States (CONUS), (b) Alaska, (c) Puerto Rico, and (d) Hawaii based on our nonlinear threshold N10 model with a 10th percentile cutoff. Cell colors note the number of 10-m cells within a 90-m grid cell where the slope-relief threshold is exceeded. Cell counts are classified using equal interval bins. Susceptibility maps do not account for the likely frequency or magnitude of landslides; this map reflects the degree to which local topographic conditions are consistent with our previously observed landslides across the country.
Oblique aerial photograph of the 2014 landslide in northwest Washington. This image shows the entire extent of the landslide source area and path. This event is commonly named the “Oso Landslide” in many official reports.

[the first photo is Queen Maeve's Cairn, on the top of Knocknarea, near Sligo - so not in the study area, but one I have had the pleasure of hiking up to see]

The Ural Mountains [geology / remote sensing]

earthobservatory.nasa.gov/imag <-- shared technical article

[(1) I am currently reading the Russia chapter of Tim Marshall’s book, “Prisoners Of Geography”, he explains - amongst many other things - how the Ural’s play SUCH an important part in the areas geopolitics and ‘military’ history, and (2) geology reflected in hydrology, fluvial and geomorphology is a specific technical interest of mine, especially with the now readily availability of remote sensing data]
