Englacial hydrology refers to networks of fractures or a well-developed ‘plumbing system’ of conduits within a glacier that drain water from the surface to a glacier’s margin or base. The following two photos by Frank Kibbe show water exiting an englacial conduit at the terminus of Lamplugh Glacier, Alaska.
Lamplugh Glacier is located in Glacier Bay, Alaska. Thanks to Frank Kibbe for contributing his fantastic photos to GlacierChange.org!
