Alaska, Kids, Nature 

From the inside cover flap:

In the heart of Alaska, surrounded by mountains, a lake appears each spring as if by magic. Winter snows have blanketed the lake bed and the surrounding land in Denali National Park for months. As the snow melts, the water slowly rises up the surrounding banks until the lake is full. With it, a complete ecosystem is reborn.

Birds and beavers, moose and caribou, hares and wolves, the animals are drawn to the lake. Some even begin their lives here -- fairy shrimp eggs lie beneath the snow waiting for the water to bring them to life. Many of nature's dramas are replayed each year in and around the lake.

Then as the days grow warmer, the lake begins to disappear, as slowly and steadily as it appeared, becoming a meadow again. Some animals in Denali National Park move on when the lake no longer serves their needs; others find the meadow to their liking until the snows once more cover the land. But they'll all return next year, just as the lake will.

Nowhere is the cycle of nature more dramatic than it is with Alaska's Disappearing Lake. Come witness the magic for yourself.
