The Lamar River is a right tributary of the Yellowstone River in the north of the US state Wyoming with a length of 40 miles. It flows along its entire length through Yellowstone National Park .

course

The Lamar River rises southeast of Parker Peak in the Hoodoo Basin in the far east of the national park in the middle of the Absaroka Range . It first flows west, turns north near Saddle Mountain and continues along the Miller Plateau into the Lamar Valley , a broad valley known for its biodiversity that is crossed by US Highway 212 . He reaches the valley near Amethyst Mountain at the confluence of Soda Butte Creek in the Lamar River. From there it flows further to the northwest and through the Lamar Canyon until it finally flows into the Yellowstone River after 40 miles near Tower Junction below the Grand Canyon of the Yellowstone . The Lamar River has a number of tributaries along its course, including Slough Creek , Soda Butte Creek, and Cache Creek.

history

In 1962, an archaeological dig was carried out in the Lamar Cave, a cave on the river, which found thousands of animal bones from around AD 400. However, human activities could not be proven.

Before the geological expedition from 1884 to 1885, the Lamar River was known as the East Fork of the Yellowstone River . During this expedition, geologist Arnold Hague named the river after Lucius Quintus Cincinnatus Lamar , the United States Secretary of the Interior appointed in 1885. The Lamar Valley and other places in the park that contain "Lamar" as part of the name are also derived from this original name. In 1869, the participants of the Cook-Folsom-Peterson expedition reached the Lamar River upstream of the canyon section flowing into the Yellowstone River and traveled upstream to the confluence with Calfee Creek , where they pitched their camp on September 16, 1869.

During the fires in Yellowstone National Park in 1988 , some areas on the Lamar River were hit hard and some of them burned down completely.

fauna

Wolf on the road near the Lamar River

Pronghorns , bison and bears , including grizzly bears , live along the river, especially in the Lamar Valley area . The Lamar Valley is one of the best places in the world to see wolves . The river valley also played a major role in the resettlement of wolves in Yellowstone National Park, for example the Druid Pack was released into the wild at nearby Druid Peak . Wolves were also introduced to the Soda Butte Creek, Crystal Creek, and Rose Creek Rivers in 1995. The Lamar Canyon and Junction Butte wolf packs live in the area along the river. This is home to cutthroat trout . Birds in the area include ospreys and bald eagles . The area is often referred to as the "Serengeti of America" ​​because of its biodiversity.

Some rainbow trout live in the river, but mostly the Yellowstone Cutthroat Trout, which are endemic to the Greater Yellowstone Ecosystem . The Lamar River and its tributaries can usually only be fished from mid-July due to the high water level. The National Park Service has mandated that the Lamar River and its tributaries, including Slough Creek and Soda Butte Creek, since 2018 require anglers to kill all non-native fish, including rainbow and brown trout .
