Lined up with Delicate Arch, 0.04 km away. Look towards 241° from north. It works across an area around this point, not only from the exact spot.

Good to know

From the east/north-east side, 20–50 m from the arch, not the classic rim of the bowl. About 5 km round trip; you walk back in the dark.

Here you choose the position: these dates say when the alignment is possible, then on site you find it by moving a few metres.

Dates for 2026–2030, worked out by Duskbox’s own astronomy engine: the sun from NREL’s SPA, the moon topocentric, both with atmospheric refraction.
