Fluvial System Block Diagrams
--
I was looking to understand a fluvial system the other day, up in the high Arctic, as I looked at 3DEP remote sensed elevation data… I have always been fascinated by the how geology, water, weather shapes a landscape, including erosion (aka geomorphology if you will) – and realized how very much value fluvial block diagrams have as we try to conceptualise what has, is and will happen(ed.)

Today #GeologyWithCats! We found this #drillcore it's a #sandstone. The white layers had large pores with #water in it. When #sediment was accumulated the pressure was growing & finally the water was squeezed out upwards-its a water escape structure.

maps - Geographic location of Grand (Big) Traverse Bay (red to green contours) along the eastern shoreline of the Keweenaw Peninsula. On the Peninsula, early copper mines are indicated by black dots within the Portage Lake Volcanic Series (dashed lines) and large stamp mills by stars. Two mills (Wolverine and Mohawk) are located near Gay. Insert shows anthropogenic copper inventory “halo” around the Peninsula, in µg/cm² copper

maps - Grand (Big) Traverse Bay: 2010 LiDAR DEM (digital elevation model) colour-coded by elevation and water depth (depth scale to right). Red horizontal contour lines are at 5 m depth intervals. Gay tailings pile (“original pile”) is indicated, as well as migrating underwater stamp sand bars dropping into an ancient river channel (the Trough; at locations #1, and #5). On the eastern flanks of Buffalo Reef, stamp sands are moving out of the Trough into cobble/boulder fields (#3, #4). Along the western edges, stamp sands have migrated as a beach deposit to the Traverse River Seawall (#8) and are slipping down into an underwater depression (#7) next to cobble/boulder fields. Stamp sands are also moving around the harbour outlet (#8). Hence, both the eastern and western sides of Buffalo Reef are experiencing tailings encroachment. Lower on the reef (#2, #6), there is little contamination. Past the Traverse River, the sands in the southern bay are almost exclusively natural quartz grains (#9), forming a white beach with shoreline cusp-like features and bar, plus ridges (#10) of natural sand moving from the shelf into deeper waters off the bay and into Lake Superior

aerial images - UAS high-resolution drone elevation and bathymetry surveys (base map 9 August 2022) of shoreline retreat at the original Gay pile location after bluff removal. Overlays along the beach edge trace shorelines in 2009, 2016, and 2022. The 78 m retreat over 6 years (2016–2022); equates to a 13 m/yr rate. The previous, nearly constant, long-term retreat rate prior to 2009 averaged 7.9 m/yr (ca. 26′) [7,57]. The original Jacobsville Sandstone shoreline, before stamp sands were discharged, is marked by the red border in the far-left upper region. Note white concrete basements of the two mills and remnants of both wooden and broken concrete launders in the northern region. Environmental recovery is beginning, as benthic organisms and fish are returning to clear underwater stretches of the bedrock shelf, where waves have removed stamp sands. Scattered trees (many birch) are beginning to colonise what is left of the original Gay Pile surface.

photos - Gay Stamp Sand Pile. (a) Wooden discharge launder distributing tailings onto the Gay Pile, around 1922, with smaller sluices conveying stamp sand and slime clays laterally (courtesy MTU Archives). (b) Photo of 6–8 m high stamp sand bluffs in July 2008 off Gay, showing a buried small lateral sluiceway protruding out of the pile along the shoreline. Lake Superior waters are to the right; the dark beach sands are stamp sands with intermixed slime clay layers. (c) Bluff photo from about the same location in 2019, when shoreline erosion (ca. 7–8 m/year) reached the buried launder support beams, just before bluff removal.

maps and photo - Abrupt cut of drainages when reaching loose materials (e.g., sands) as revealed on a geologic map; the same location in the map is shown in the attached photo

annotated image maps - The images above show the current drainages existed on SRTM DEM; while the image below is a processed ALOS PALSAR image showing traces of delta-like shape paleodrainages (DPl); but they do not coincide with the current drainages in the SRTM DEM (image above). Triangle at point S1 is the site where the stratigraphic sequence was investigated.

photo - sand meets the rock outcrops, Hafar Al Batin desert

annotated image maps - he image above shows a shaded figure for an odd paleodrainage (OPl) as shown on the processed ASTER image. The same ASTER image was used below after projecting the current drainages extracted from STRM DEM. There is no coincidence between the OPl and the current drainages evidencing an invisible paleodrainage (OPl). Triangle at point S2 is the site where the stratigraphic sequence was investigated

@fff the funny thing is : there was a year long study if its possible to find markers for the Anthropozän
you, he - we all - may watch this : https://www.youtube.com/watch?v=v1M5dDuh1VQ

which (only) prooves that humans leave many distinct and significant marks in earth climate and geological processes.
