GigaPan w/Canon SD850


Thick sequence of Jurassic-aged conglomerates exposed in Durham, CT.

The sediment in these rocks were deposited as alluvial fans off the Eastern Border Fault and later lithified. The sediment doesn't travel very far from the original rock source, so the pieces are large and poorly rounded.

As with our earlier pan of this rock unit - www.gigapan.org/viewGigapan.php?id=18781 - there's a good reason why we didn't get closer!
