"It may be hard to imagine, but from 400 million to about 130 million years ago an ocean covered the area we know as the Sierra Nevada. Beneath the seafloor, geological processes were at work that would lead to the formation of the Sierra Nevada mountain range. Plate tectonics, the movement of the plates that form the earth's crust played an important role, and is also responsible for the volcanic and seismic activity we experience today. During the late Paleozoic Era, approximately 250 million years ago, the pressure and friction that resulted from the grinding of the converging North American and Pacific plates as they moved past each other caused the crust of the Pacific plate to melt, forming plumes of liquid plutonic rock that eventually floated up toward the surface.
These plutons came together to form the single, massive batholith, or deeply imbedded rock, that is the Sierra Nevada. As the batholith began to rise, about 80 million years ago, the layer of marine sedimentary rock that lay over the mountain was gradually eroded away and deposited in the valley.
However, remnants of the marine rock, called roof pendants still cling to mountaintops. Because the uplift was greatest on the eastern side of the batholith, the mountain range tilts toward the west, creating a gradual western slope and a precipitous incline on the eastern side."

This image is Heart Lake, one of my favorite spots to relax along the Rock Creek Trail.

A beautiful place, I can see why its among your favorite to relax, who could not be inspired by a sight like this. The lush green, the forest, the snow capped peaks and a perfect reflection to top it all off. Beautiful place and yet another great name too.

You're capturing well this landscape by a good angle and excellent tone/clarity, so it's interestig and impressive to see the calm/clean lake, the wood with lush green and steep rock mountain with glacier. It's the beautiful panoramic view. And, the reflection projected to the lake draws out a good effect.
