Massive rounded granite monolith named for a weathered basin near its summit. It is a distinct named City of Rocks landmark with established nearby parking and trails.
Arco, ID
A named crater feature in the North Crater area offering a close look at the monument's cinder-cone terrain. Stay on signed routes; fragile lava surfaces and steep crater slopes should not be shortcut.

A remarkably clear spring complex that forms the headwaters of the Henrys Fork. The developed public viewing area offers a reliable nature stop without sending visitors into sensitive backcountry.

One of North America's largest springs bursts from the canyon wall and feeds an intensely clear stream. Trails are steep in places; remain within the state-park preserve.

Long rounded granite formation whose shape inspired the 'Bread Loaves' name, standing among the reserve's most recognizable rock forms. Stay on public reserve routes.

Bruneau, ID
Home to North America's tallest single-structured sand dune, rising above a pair of small lakes. The stark dune field is a major natural oddity and also a well-known dark-sky destination.
Wallace, ID
At the intersection of Bank and Sixth streets, Wallace marks itself as the Center of the Universe, a deliberately tongue-in-cheek civic landmark that fits OddWay almost perfectly. The marker is in the public street intersection; view it from the surrounding sidewalks and crosswalks.

BLM overlook above the Snake River Canyon within the Birds of Prey conservation area, with a short interpretive trail and dramatic basalt cliffs. Stay behind barriers and on signed paths.

Visitor center overlooking one of the tallest straight-axis concrete gravity dams in North America. Exhibits explain the huge Clearwater River engineering project and the reservoir behind it.

A homemade assemblage of old mining and logging parts that sprays water into a whimsical roadside fountain. It is one of the Silver Valley's stranger quick stops.
Twin Falls, ID
Public monument interpreting Evel Knievel's 1974 attempt to jump the Snake River Canyon in a rocket-powered Skycycle. This pin intentionally uses the visitor center rather than the privately owned jump-ramp site.

Nature preserve with unusual spring-fed pools and travertine formations created by mineral-rich water. Stay on established public routes to protect fragile formations and habitat.

Large open-air mural gallery filling an alley in downtown Boise, continually changing as artists add new work. Public pedestrian access makes it a strong low-friction OddWay stop.

Designated public overlook across the Hagerman fossil landscape and Oregon Trail corridor. Fossil collecting and off-route access are prohibited; OddWay should keep users at signed public viewpoints.
