After a two-year GIS modeling project, the researchers chose the six ice patches they are studying after two years of flying around in late summer and looking for large bodies of ice and snow ringed with dark colors-often the pellets caribou dropped centuries ago. The ice patches are melting to reveal ground that hasn't seen the sun in hundreds, or thousands of years.

"As climate change continues, (the exposure of artifacts from melting ice patches) will go on for some time," Dixon said.

In addition to arrow shafts, a copper arrowhead, the birch basket, and an old caribou hide, the scientists and Park Service personnel also saw more modern things during their travels in the Wrangells, including the remains of a roadhouse built on a glacier on one of the gold rush routes from McCarthy to Chisana.

"It's a whole roadhouse that's flowing down the glacier," Dixon said.

Manley, the geologist who found the birch-bark basket, said looking for artifacts on the edge of ice patches is not only interesting science, it's great fun. The scientists usually have only a short window of time to search the base of an ice patch while a helicopter waits for them.

"Finding such a well-preserved artifact melting out of a glacier is something like winning when you're gambling," Manley said. "After going hours, or days without finding another one, you develop an urge to find more."
