Thistle UT — landslide site (historic)

Safety: cautionoverlook

Thistle, UT

Union Pacific

Access & safety

Public access

Site of the 1983 Thistle landslide that buried the original UP main and rerouted both road and rail. Public US-6 and US-89 pullouts pass the landslide scar and the rebuilt railroad alignment. The drowned remains of Thistle townsite are still visible from the highway. The active UP Provo Sub passes through the new alignment.

Safety notes

US-6 / US-89 are busy roads — park well off, set hazards. The Thistle area is geologically active; rockfall is possible after wet weather. The rebuilt rail tunnel and slide-prevention infrastructure are UP property; do not approach.

Parking

Roadside pullouts along US-6 / US-89 in the Thistle area. The Thistle Tunnel approach has informal capacity.

Best time of day

Morning best — east-facing canyon walls. The narrow alignment limits direct sun to a few hours daily.

Train frequency

High — same UP Provo Sub traffic that runs over Soldier Summit. 25-40 trains/day.

Nearby

Thistle (the historic townsite) is essentially abandoned. Spanish Fork (~12 miles north) and Helper (~30+ miles south) have services.
