Hamburger Area Rock Climbing

Per Brent Frazier: the raptor closures have been lifted in the Lumpy Ridge and Loch Vale Areas ( nps.gov/romo/raptor-closure…)

Each year, Rocky Mountain National Park initiates temporary closures in certain areas of the park to ensure that birds of prey will be undisturbed during their breeding and nesting seasons. These closures begin on February 15 and continue through July 31, if appropriate. Monitoring by park staff and volunteers have determined that all remaining closures can be lifted on July 28, 2023.

Per Matt Coghill: the Golden eagle nesting activity has extended Lumpy closures through Aug. 15, 2022 on Sundance, Thunder Buttress, and Needle Summit!

Per A.Eaton: the raptor closures have been lifted as of 6/4/2022 at Lumpy for the following formations:

Twin Owls
Rock One
Batman Rock
Batman Pinnacle
Checkerboard
Lightning Rock

Per the Denver Post: as of Feb. 15, 2022, Checkerboard Rock, Lightning Rock, Batman Rock, Batman Pinnacle, Sundance, Thunder Buttress, The Parish, Bookmark Pinnacle, The Left Book, Bookmark, Twin Owls, Rock One, and the Needle are closed for raptor nesting. These closures will continue through July 31, 2022 if needed.

All areas [were] OPEN to climbing for the 2021 post July season.

Closures ending July 31:
Batman Rock, Batman Pinnacle, Lightning Rock, Checkerboard Rock - nps.gov/romo/planyourvisit/…
Sundance - nps.gov/romo/planyourvisit/…
The Book Area: Left Book, The Bookmark, Bookmark Pinnacle, and the entire Book formation (including Renaissance Wall, Isis Buttress, Pages Wall Area, and J-Crack Slab Area)- nps.gov/romo/planyourvisit/…
Thunder Buttress and The Parish - nps.gov/romo/planyourvisit/…
Twin Owls and Rock One - nps.gov/romo/planyourvisit/…
Cathedral Wall - nps.gov/romo/planyourvisit/…

When closed, the closures include the named rock formations and the areas surrounding the base of the formation. This includes all climbing routes, outcroppings, cliffs, faces, ascent and descent routes, and climber's access trails to the formation.

Areas not listed are presumed to be open. These closures will be lifted or extended as conditions dictate.

Approaching from the front side of lumpy goes through private land. Access isn’t possible by starting on the Gem Lake trail and cutting off to head south.
