A small #outcrop of the #Squantum Member of the #Roxbury #Conglomerate
These #rocks are in the #BostonBay Group, which is currently dated to #Neoproterozoic. The Squantum Member was interpreted as a #tillite, possibly associated with the #Gaskiers #glaciation, although there a scant signs like scratched pebbles or faceted cobbles. It is currently commonly interpreted as a #debrite (debris flow). Details in captions.

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.

@jfh @wutrain yes that's a cute little pup in that backpack. I rode with the #Roxbury group. We were small but mighty and ended up having about double the riders we had last year #BostonBikeBoom
Here we're at the start of the route in #FranklinPark. These 2 riders both have #FoldingBikes of different designs and generations

Nice article on the Roxbury Photographers Training Program (RPTP) of the 1960s-70s, a project of MIT's Creative Photography Laboratory. which aimed to teach young Roxbury residents how to become professional photographers.

Fort Hill, #Roxbury Crossing, #Boston, #Massachusetts,#USA
Fort Hill is named for the fort (not this tower!) erected on it between the confrontation at Concord in April 1775 and British evacuation of Boston when Washington et al. moved guns onto #Dorchester Heights in March 1776 (independence “declared” in July 1776). The hill is capped by the Roxbury Conglomerate (#Neoproterozoic, ~600 Ma), which sports rakish #Pleistocene glacial striations. #history #geology #Fujifilm #glacial #NewEngland
