Loess Bluffs National Wildlife Refuge

Loess Bluffs lies along the Central Flyway, one of the broad aerial highways that migrating birds follow between their northern breeding grounds and their southern wintering grounds. Wetlands like this one are essential rest stops, places where exhausted birds can feed and gather strength before continuing a journey that may span a continent. The refuge was established to protect exactly this kind of habitat as the great marshes of the interior were being drained for farms.

The refuge's marshes, pools, and moist grasslands are managed to provide food and safe water for the millions of waterfowl and other birds that pass through each year. In the off-season it is a quiet place of herons, muskrats, deer, and resident birds, but its true purpose reveals itself in the crush of the spring and fall migrations, when the sky itself seems to move.

The signature event is the snow goose migration. As the birds funnel down the flyway, huge numbers stop here, and at peak the refuge can hold flocks numbering in the hundreds of thousands. When a flock takes flight all at once, the sound is a roar and the sky turns white, a wall of wings that has to be seen to be believed. It is regularly ranked among the finest wildlife spectacles in the region.

Where there are that many geese, there are eagles. Bald eagles gather at the refuge during migration in remarkable numbers, perching in bare trees and along the ice to hunt weakened or injured birds. Watching hundreds of the national bird patrol a marsh crowded with geese is a rare thing, and it draws photographers and birders from across the Midwest during the peak weeks.

The refuge takes its name from the Loess Hills that rise steeply along its eastern edge, and they are geological oddities in their own right. Loess is fine, wind-blown silt, and at the close of the last Ice Age, winds picked up vast quantities of this dust from the barren floodplains of the Missouri River and piled it into ridges along the valley's edge. Deep deposits of this kind are found in only a couple of places on Earth.

The result is a range of unusually steep, sharp-crested hills with their own specialized plants and animals adapted to the dry, well-drained soil. Rising directly above the flat, wet marshland, they give the refuge a striking layered profile: hills of ancient dust looking down on a wetland alive with wings. Trails and overlooks let visitors take in the contrast.

The heart of a visit is the auto tour route, a driving loop around the pools and marshes that lets you watch the wildlife from your vehicle, which doubles as a moving blind that keeps the birds from spooking. Pullouts and overlooks let you stop and scan the water, and early morning and late afternoon bring the most activity as the flocks move between roosting and feeding.

The great numbers come with migration, so timing matters: late fall for the southbound push and late winter into early spring for the return are the classic windows for the snow geese and eagles. Bring binoculars or a scope, dress warm, and be patient, and you may witness the moment when the whole marsh rises into the air at once.
