(AP) — The creators of a trail plan for Scotts Bluff National Monument in western Nebraska are seeking public input on their proposal.

The 30-day public comment period opened on Monday. The plan has been under development for more than a year.

The final plan adds about 10.5 miles to the existing 4.5 miles of trails around the monument. It includes options to connect monument trails with the Monument Valley Pathways system, loop trails in the park’s southwest corner, and create a pathway that traces old Oregon Trail ruts.

An open house is scheduled for the evening of July 30 at the Farm and Ranch Museum. The event will include a short presentation.
