Bering Land Bridge National Preserve

Lost Jim Lava Flow, Bering Land Bridge National Preserve

A vast expanse of lava rock covers the tundra, small plants and lichen are reclaiming the lava field at Bering Land Bridge National Preserve

"Less than 2000 years ago, the Lost Jim Lava bed was formed from slow moving lava spreading on top of the much older Imuruk lava field. This flow occurred with the top layer of lava cooling as the bottom layer continued moving. The movement of the flowing bottom layer created waves in the hardening top layer. When the lava cooled and turned to rock, the waves become wrinkles in the lava. The smooth wavy texture of the Lost Jim Lava Flow contrasts the broken look of the surrounding Imuruk Lava field which has experienced thousands of years of weathering."

Threatened And Endangered Parks: Alaska

As delegates from nearly 200 countries gathered for the recent international conference on climate change, U.N. Secretary-General Antonio Guterres decried the “utterly inadequate” global response to the crisis so far. He warned that the “point of no return is no longer over the horizon” but that “It is in sight and hurtling toward us.” Nowhere are the consequences more visibly “hurtling,” and landing, than in Alaska. And in the northern state’s national parks and preserves, that means growing pressures on the very resources the National Park Service is charged with protecting.

An Ice Age Survivor

Dating back to about 187,000 to 129,000 years ago, muskoxen are known as the shaggy survivors of the Ice Age. Today muskoxen are found in northern Canada, Greenland, and Alaska. Inupiaq speakers call them itomingmak, meaning "the animal with skin like a beard" for their distinct fur that hangs down nearly to the ground.--National Park Service, Bering Land Bridge National Preserve
