Here, the prominent granite is Cretaceous and overlies coeval layered diorites, as in Torres del Paine. Mount Pinchot and the dark rocks at right-center are a continuation of the metamorphic screen under Split Mountain, and the Cretaceous Striped pluton likely sits above this screen in a manner similar to the Tinemaha Granodiorite on Split Mountain. See Bartley et al. (2012) for details. https://www.allenglazner.com/field-notes/torres-del-paine-vs-split-mountain-california-2 monthly 0.5 2025-05-30 https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/588cc654-4c7c-4e3c-b470-e5efd093ac3e/Geology+Illustrated+title+page.jpg Field Notes - Torres del Paine vs. Split Mountain — 2 — Split Mountain - Make it stand out Title page of Geology Illustrated https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/8493f2a6-a988-4b27-845c-c900abd9f10a/Cardinal+Pk.%2C+Split+Mt.+DSC_0014-10+2005+afg.jpg Field Notes - Torres del Paine vs. Split Mountain — 2 — Split Mountain - Make it stand out Sierran range front, looking west in morning light, from Highway 395 south of the Poverty Hills. White leucogranite is overlain by dark brown metasedimentary rocks that are in turn overlain on Split Mountain by dark gray granodiorite. It’s a twofer—a pluton roof and a pluton floor in one photo. Split Mountain is the large peak on the right with its characteristic V notch, and the minor peak on the left, at the end of a long aréte composed of metasedimentary rocks, is Cardinal Peak. https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/4ba7bb31-d1f1-4e4e-8412-ea7a59b0ab0b/Shelton+Split+Mt.jpg Field Notes - Torres del Paine vs. Split Mountain — 2 — Split Mountain - Make it stand out Shelton’s photo of Split Mountain, looking northwest over Mather Pass and Palisade Creek.

Abundant NW-striking dikes are evident in the leucogranite, but these cut the brown metamorphic rocks as well. The cirque on the right is occupied by rock glaciers. https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/53a229c5-e042-42f6-b530-831e4c1e13ad/Cardinal+Lake+with+John%2C+late+afternoon.jpg Field Notes - Torres del Paine vs. Split Mountain — 2 — Split Mountain - Make it stand out Late-afternoon light on the east side of the Cardinal-Split aréte. Abundant mafic and intermediate dikes of the Independence swarm cut both the leucogranite and the capping metamorphic rocks.

Highly jointed and locally iron-stained leucogranite is overlain by brown metasandstone correlative with the Cambrian Campito Formation, with a bit of greenish Cambrian Poleta Formation atop Cardinal Peak. https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/6d811ffb-1e64-49b2-9468-11f8643a79f6/Split+Mt.-Cardinal+Peak+ar%C3%A9te.jpg Field Notes - Torres del Paine vs. Split Mountain — 2 — Split Mountain - Make it stand out Closeup of the Cardinal-Split aréte. Layering in the metasedimentary rocks is subparallel to the roof contact, and dikes of granite cut these roof rocks. Here and elsewhere there is no sign of any blocks of the roof rocks within the granite. https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/3de630f4-b609-47ec-a23d-dac9214ae865/Split+Mountain.jpg Field Notes - Torres del Paine vs. Split Mountain — 2 — Split Mountain - Make it stand out Aerial view of Split Mountain from ~4000 m altitude, looking northwest. Leucogranite, locally stained deep orange, underlies dark brown metaclastic and buff metacarbonate rocks. These are in turn overlain by dark gray Jurassic Tinemaha Granodiorite. In Shelton’s black-and-white photograph the metamorphic rocks and granodiorite are barely distinguishable. Nevertheless, this is an excellent example of a flat-lying pluton floor that extends over several square km in this area (Bartley et al., 2012). Intermediate and mafic dikes cut through all the units. These are locally up to 10 m thick, and are highly composite. https://www.allenglazner.com/field-notes/patagonia-march-2025-1 monthly 0.5 2025-05-28 https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/1748370299601-JHNO34AVL9V7JNGZYOVS/Granite+dikes+and+sills+in+Cuerno+Principal+OM553697+2025+afg.jpg Field Notes - Torres del Paine vs. Split Mountain — 1 — Cuernos del Paine - Make it stand out Granite dikes and sills in Cuerno Principal.

This part of the road is typically buried by flood debris washed down Gower Gulch during storms, and the bulldozed material on the left is debris from the last time the road was cleared. https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/8bd4c448-aeea-4df2-b8bf-d3a7654fd867/Sediments+in+eroded+fan%2C+lower+Gower+Gulch.jpg Field Notes - Badwater Road is Really Screwed Up - Make it stand out OK, this may not be a spectacular photo, but it tells an interesting story. The vertical wall, carved in the old, pre-diversion fan, consists of young volcanic and sedimentary material from Gower Gulch proper. The much larger rocks littering the bottom of the active wash are exotic to the area and were carried down Furnace Creek Wash and then down little Gower Gulch. The larger floods that carried them were quite effective at cutting down into the old, soft fan. Twenty feet and counting. https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/9ec5ce05-5643-46ff-bfe1-967b3412022a/Gower+Gulch+flood+Badwater+Road+Death+Valley.jpeg Field Notes - Badwater Road is Really Screwed Up - Make it stand out Flood debris from Gower Gulch across Badwater Road in 2017.

There is no trace of it left now owing to road grading and flooding. The current parking area (which may have been ripped up in this month’s floods) covers most of where it was. Note the small streams that had already formed across Furnace Creek Wash just south of the berm, heading for the newly blasted cut into Gower Gulch. https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/71c23e9e-cebe-43a2-8745-c430137cbd08/Gower+road+damage+1973.jpg Field Notes - Death Valley Flooding 2022: The Futile Diversion Attempt at Gower Gulch - Make it stand out Looking east from Zabriskie Point toward Highway 190 in 1973.

The recent floods likely overran and washed away this berm, because cars in the parking lot behind it were partially buried by flood debris. https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/084d309a-d304-49ab-a974-2adc8dcfe5c9/Furnace+Creek+Wash+35+mph+sign.jpg Field Notes - Death Valley Flooding 2022: Trying to Tame Furnace Creek Wash - Make it stand out Dropping down Furnace Creek Wash toward the Inn, motorists are advised to slow down to make the sharp left turn.

White values are time units (say, seconds) that a P-wave takes to cross that square; these are a priori data, observed, perhaps, by measurements in drill holes. Seismic travel-time studies have yielded the “Observed” values for total travel time in a given column or row (e.g., 18 for a wave traversing the first column). Your job is to fill in the blank squares so that your model values make the "Model” sums for rows and columns (red values) match the Observed values, in which case the differences will be zero. https://www.allenglazner.com/teaching-notes/announcing-teaching-notes monthly 0.5 2025-06-02 https://www.allenglazner.com/home daily 1.0 2025-06-09 https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/1652051903707-KB41RSJU3M6E8GEFQH6P/El+Capitan+-+7+DSC_0036+2004+afg.jpg Home https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/1652052665571-6RIYXUIGQYGGYLICM7X0/Geol+72H+at+Convict+Lake%2C+Laurel+Mt.+IMG_1431+2014+afg.jpg Home https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/1652052814468-TLGACGMO58P3ELAFJY2K/GUDVEC+cover.jpg Home https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/1652058139662-R7YDB60R2G306PHIEBZ2/Fallout+tephra+near+Little+Hebe+possible+cover+P1030039+2016+afg.jpg Home https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/4628722f-3f6a-461d-8576-8e39d6bfc7db/View+of+distant+San+Francisco+Peaks+and+wildfire+smoke+from+Grand+Canyon+Lodge%2C+North+Rim+OM511608-Enhanced-NR+2024+afg.jpg Home https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/caeefc74-cc3f-4442-8dd1-6b38968c21c6/Ventifacts+Death+Valley.jpg Home Mars or Earth? https://images.squarespace-cdn.com/content/v1/627832604c176c1faa62d7c9/82de4810-df31-4621-9e31-80c6ff9a1021/Grand+Canyon.jpg Home Is the scenery at national parks basically geology?
