  1. #Day20 theme is Outdoors (Map of mountains, trails, etc.). I wanted to try draping a geologic map over a DEM and chose one of my favorite places Pitkin County, CO with the Maroon Bells area. Blue color: Maroon formation; Red: granodiorite; Yellow: surficial deposits.

    Tools: ArcPro Local Scene
    Data: National Geologic Map Database ngmdb.usgs.gov/ngmdb/ngmdb_hom

  2. Cheverie Point, Johnson Beach, Rainy Cove, Nova Scotia Geology Field Trip

    Someone has kept a very nice blog of all things Nova Scotian geology including the field trip below. Having a look at the geologic map of the area immediately convinced me that Nova Scotia has some amazing geology. I had to see more.

    On the geology map in the image below, the area of the field trip is along the south side of the Bay of Fundy just to the east of the word β€œMinas Basin” and starts at the left limb of the cove where the letter F in bold is circled. If you would like a better look at the map, and I highly recommend it, it’s linked below. It’s a pdf and takes a few to load. The legend has all the symbology for the features on the map including the rock types and ages. There are some beautiful cross-sections that interpret the subsurface geology. A true work of art.

    The blog (linked below) shows the folded faulted rocks in detail as they search for the Kennetcook thrust fault. Spoiler alert - they find it.

    BTW, the blog was discontinued September 2022, but treasures like this should never be passed up
