We flew our 500 MHz radar system out to Columbia Glacier on May 1. The radar wave reflects off of density transitions in the snow, allowing us to estimate the thickness of the winter accumulation. By flying glaciers on both the coastal and interior sides of the range, we should be able to estimate precipitation gradients across the whole area. It was a really nice day. As with all of my research photos, full resolution copies are available at no charge for scientific or research purposes.
