Any #glacial geologists/geomorphologists wish they could see inside an #esker? There's a place in north #Norfolk where you can.
Lidar image and three photos here. Uppermost preserved layer contains densely-packed, well-rounded flint cobbles, indicating powerful water flow.
N.B. car keys included in close-up photo for scale.
The Skystone is a #glacial #erratic boulder in Bonney Lake, #Washington state. It was deposited approximately 13,000 years ago. It has over 20 pits pounded into its surface, presumably by members of the #Puyallup tribe. The holes seem to point towards both #astronomical and geographic features. #FolkloreThursday More: https://www.megalithic.co.uk/article.php?sid=58988 #folklore #archaeology

I wonder if it ever annoyed Kubrick that his creative process took so long? Like, did he ever have exec types turning him down for work because they knew he didn't crank out product like a gumball machine, & maybe he wished he could work faster like everyone else? I mean, I can see him being pure confidence, but, as someone who creates with a similar meticulous, against-the-grain pace, I end up with horrible doubts, & lots of rejection, etc, etc, & I just wonder.

#Juneau’s record glacial outburst flood prompts evacuations and destroys at least 1 home
August 5, 2023 by Anna Canny, KTOO
"The source of this weekend’s #flooding is a #glacial dam outburst flood from #SuicideBasin, above the #MendenhallGlacier. An update from the National Weather Service described record flooding of waterways and low-lying areas, along with flooding 'in areas that have not previously seen flooding before.'"

Anomalous pebble in layered #sedimentary #rock
An angular pebble is conformably surrounded by argillaceous and sandy layers in this #photograph of the #Neoproterozoic #Squantum Member of the #Roxbury Conglomerate. The wide range of clast sizes led to an interpretation as a #glacial #tillite thru the 1970s, but the Squantum Member is now mostly interpreted as a #debrisFlow (#debrite or #turbidite). My #photo.

Deformed bedding in meta#sedimentary #rocks
The horizontal bedding of the #Squantum Member of the #Roxbury Conglomerate (#Neoproterozoic, #Boston Bay Group) has been disturbed locally.
In the #glacial #tillite interpretation of the Squantum (favored through at least the 1970s), the distortion might be caused by glaciotectonic drag at the ice base. The current interpretation as a #debrite or #turbidite would probably attribute the deformations to synsedimentary slumping. My #photo. #fieldTrip

Rapid changes in #clast size in #sedimentary #rocks
The #Neoproterozoic #Squantum Member of the #Roxbury Conglomerate (#Boston Bay Group) transitions from sandstone, to almost-clast-supported conglomerate, to laminated argillite…in about 25 cm. Fifty years ago, it was interpreted as a #glacial deposit and called the Squantum #Tillite, presumably associated with the #Gaskiers Glaciation. Paucity of evidence (e.g., few scratches or faceted clasts) suggests a debris flow. My #photo.

The #glacier went that-a-way
The #striations on this face of the #Ediacaran (ca. 560 Ma) #Squantum Member of the #Roxbury #Conglomerate were probably left by the #Pleistocene #Laurentide ice sheet, which retreated ca. 12 ka. The striations have the right orientation, from northwest to southeast.
The Squantum Member was once interpreted as a (#glacial) #tillite. The most common contemporary model is a peri-#Gondwana #debrite (#turbidite).

Interbedded argillaceous & tuffaceous #sediments
These photos are of #Cambridge #Argillite, exposed above the #Squantum Member of the #Roxbury Conglomerate (#Neoproterozoic). Prior to the 1970s or so, the Squantum Member was interpreted as #glacial sediments; it's now broadly interpreted as debris flows, with the Cambridge being distal turbidites overlying it. I lead a field trip here for #UMassBoston. See captions.
