HiPOD: Layered Deposits In Uzboi Vallis

HiPOD: Layered Deposits in Uzboi Vallis

Layered deposits in Uzboi Vallis sometimes occur in alcoves along the valley and/or below where tributaries enter it. These deposits may record deposition into a large lake that once filled Uzboi Vallis when it was temporarily dammed at its northern end by the rim of Holden Crater and before it was overtopped and breached allowing water to drain back out of the valley.

Layered deposits similar to those here may remain preserved where they were protected from erosion during drainage of the lake. Data from the CRISM instrument onboard MRO shows that clays are within these deposits that may differ from clays found elsewhere on the valley floor. Hence, the clays in these layers may have been washed into the lake from surrounding clay-bearing surfaces. (Enhanced color cutout is less than 1 km across.)

that one unforgettable summer

We’re going BIG this Fossil Friday. Like, really big. 🦕At 122 ft (37.2 m) long, Patagotitan mayorum is the Museum’s largest dinosaur on display and one of the largest animals to have ever walked the Earth! This gigantic herbivore, which lived some 95 million years ago during the Late Cretaceous, was heavier than 10 African elephants—tipping the scales at roughly 70 tons. In fact, The Titanosaur is so big that it barely fits in the Museum’s halls: It’s longer than the gallery it sits in—and its head, which would graze the ceiling, extends outwards toward the elevator banks! We're open daily from 10 am-5:30 pm! Plan your visit.
