I thought I would have trouble finding G photos, but I came up with a few.
First, Great Sand Dunes. We hiked up to High Dune at sunrise and got some amazing shots. I highly recommend the journey.
This shot is from the first time I went to the Grand Canyon. We hiked down to Plateau Point and up again in about 8 hours. It is a tough hike, but definitely worth it.
Here is some Gypsum from Lake Lucero in New Mexico. These crystals are weathered into the white sand that makes up White Sands National Monument (saving that one for W).
I didn't even realize that these where all Geology pictures. You would think, being a geologist in training, that would have been the first thing I thought of. I didn't even think about geology as being a g word today. Thanks guys for cluing me in :)
