NPS honors Lewis and Clark volunteers in Kansas City

Five members of the Missouri-Kansas Riverbend Chapter of the Lewis and Clark Trail Heritage Foundation were recently honored by the National Park Service for their volunteer work to enhance the Lewis and Clark National Historic Trail. The 4,900-mile trail of the 1803-06 expedition follows the Missouri River through the Greater Kansas City Area.

At the chapter’s semiannual meeting in February, attended by 56 members, Karla V. Sigala, the National Park Service’s interpretive specialist for the historic trail, presented volunteer pins and award certificates to Yvonne Kean, Karen McKeever, Jimmy Mohler, Diane Pepper Pickman, and Dan Sturdevant.

“A lot of important work happens that would not happen without the efforts of volunteers,” said Sigala, who is based in the National Park Services’ Omaha, Neb., headquarters for the Lewis and Clark National Historic Trail.

The value of volunteerism for the national trail and local trail segments is significant. On the national stage, for example, 2,600 volunteers from 52 Lewis and Clark sites and partnerships contributed 164,593 hours of service in the fiscal year 2019, an equivalent of 78 full-time NPS staff members and a labor value of more than $4 million, according to the recently released National Park Service annual report.

The backgrounds of volunteers widely range from people with a personal interest in history, college history professors and researchers to interpretive re-enactors, biologists, natural resources specialists, and, among many other fields, students and educators in public and private schools.
