Hyatt Prairie Road: The Shortcut Between Them

10 miles connecting Highway 66 near Green Springs Inn to Dead Indian Memorial Road, past Hyatt Lake. Narrow, mostly single-lane in character and rougher pavement than either road it connects — but it turns the two into a genuine loop instead of an out-and-back.

Narrower and rougher than the two roads it connects; treat it as a deliberate, slower link between them rather than a road to carry speed on. Check current access · Reviewed 2026-09-23

Planning the drive

This is the link that turns Highway 66 and Dead Indian Memorial Road into an actual loop instead of two separate out-and-back drives: 10 miles past Hyatt Lake, climbing to 5,049 ft. 19 counted bends over that distance at a 2.0 per mile density — similar density to Highway 66 itself, but narrower and described by people who drive it regularly as mostly single-lane in character with rougher pavement than either road it connects.

Treat this as the deliberate, slower link in the loop rather than a road to carry speed on — the payoff is completing the loop, not the segment itself. It's the kind of road that rewards knowing it's there rather than one that shows up in general trip-planning searches.
