from what time period are most of the rocks in glacier national park
Glacier National Park (U.S.) The rocks found in the park are primarily sedimentary rocks of the Belt Supergroup. They were deposited in shallow seas over 1.6 billion to 800 million years ago. During the formation of the Rocky Mountains 170 million years ago, one region of rocks now known as the Lewis Overthrust was forced eastward 50 miles (80 km). This overthrust was several miles (kilometers) thick and hundreds of miles (kilometers) long.[45] This resulted in older rocks being displaced over newer ones, so the overlying Proterozoic rocks are between 1.4 and 1.5 billion years older than Cretaceous age rocks they now rest on.[45][46]
Cumberland Gap Famous in American colonial history for its role as a key passageway through the lower central Appalachians, it was an important part of the Wilderness Road and is now part of the Cumberland Gap National Historical Park.
Glacier National Park (Canada) The park contains high peaks, large, active glaciers, and one of Canada's largest cave systems. Its dense forests support populations of large mammals, birds, and alpine species. The region is noted for its heavy snowfall. The park has an extensive network of trails, three campgrounds, and four backcountry huts and cabins. Due to the major transportation routes that bisect it, Glacier National Park sees large numbers of visitors.

Desert National Park Flora: ronj, palm trees, ber, dhok.
Backshore Sediments in this area are well-sorted and well-rounded. Its grain sizes are mainly coarse sand and medium sand, which are larger than that in littoral barrier dune.The sedimentary structures include parallel bedding and low-angle cross-bedding.
