Grand Canyon Caverns (L37) has 1 runway. Runway 05/23 is 5,100 ft long and 45 ft wide. The surface is gravel. The field elevation is 5,397 ft MSL. No control tower is listed, so use standard non-towered procedures and monitor the CTAF as appropriate.
No ILS runway ends are published for this airport. That matters for planning in marginal weather. Check the current FAA Chart Supplement for the latest airport data before departure. No runway-specific noise abatement notes are published. No LAHSO notes are published. The runway system is simple, but the gravel surface and high field elevation deserve attention during performance planning and landing rollout.

Traffic pattern
Pattern altitude is not published. For light piston operations, use the standard 1,000 ft AGL pattern unless local procedures or ATC say otherwise. With no control tower, pilots self-announce and self-sequence in the pattern. Keep a sharp lookout and plan for normal non-towered traffic flow.
No right-traffic exception is published. No runway-specific pattern notes are published. The single runway layout keeps the pattern straightforward, but confirm winds and density altitude before joining. Use the current FAA Chart Supplement for airport remarks and runway data.
Every end, one page
Each runway end has its own page with wind component, traffic pattern geometry and ILS for that specific direction.
