Eskers
Glacial Erosion formed Yosemite Valley and the Sierra Nevada
A glacial lake is typically a result of both erosion and deposition. Glacial erosion carves out depressions in the landscape, creating basins where water accumulates. Meanwhile, glacial deposition can form moraines or other features that dam up water and contribute to the formation of a glacial lake.
Glacial errosion
Glacial erosion requires movement. Thus, glacial erosion begins as soon as the glacier starts moving.
Well really the valleys BETWEEN hills form by glacial and/or other erosion. The hills are what's left behind.
my conclusions are either glacial or solar
A 'U' shaped valley indicates glacial erosion.

Erosion and weathering
The 3 main types of glacial erosion are plucking, abrasion and freeze thaw.
Eskers
No, eskers are not caused by glacial erosion. Eskers are long, winding ridges of sand and gravel that are formed by meltwater streams flowing in tunnels within or under glaciers. Glacial erosion refers to the process by which glaciers carve and shape the land through the movement of ice and debris.
