Per bishop triphosphate: the prior info made it seem like the the trail was open (it's very much not). There are many signs at the trailhead. Here is an article from yesterday where OSMP says there is currently "no timeline to reopen trail to Boulder Falls": denver7.com/news/local-news….

This was added to clarify the only access to Lower Dream is to hike all the way down from Upper Dream Canyon.

From Gregger Man: there was a major rockfall at Boulder Falls. The City of Boulder had closed all access from that direction through the Keyhole. Apparently, it is now open.

From Rick Vermeil: they have finished construction on the Boulder Falls project, and it has been open to tourists and climbers for at least a couple years now. They have legitimized the climber access trail with signage to go up and over the barriers they created to prevent erosion on the west side of the canyon.

The Boulder Falls Trail was be closed to the public around the 2013 floods for a few years. Accessing the climbing areas in Lower Dream Canyon (Plotinus Wall) from the Boulder Falls Trail was off limits. In addition, the slopes above the Boulder Falls Trail were closed to access.

Dropping into Lower Dream Canyon from the Upper Dream Canyon access point crosses private property and is not permitted by the landowner. Previously, climbers accessing this area from Upper Dream Canyon were trespassing.

Fortunately, with great work and cooperation, this situation seems to have been resolved peacefully.

Per Dan Gozdz: I reached out to OSMP and received the following reply about access: yes, there is now a designated climbing access trail through Boulder Falls that follows the old footpath through the Keyhole. Enjoy!

K. Armstrong, Public Affairs Specialist, Nat'l Forest Service: as of 6/8/21: BC areas reopen after unsuccessful nesting.

K. Armstrong, NF Ranger 7/29/20: following a 5 mo. closure to protect nesting eagles, the Roosevelt NF reopened Eagle Rock.

“The BC eagles successfully raised 1 strong & healthy eaglet this year,” wildlife biologist Aurelia DeNasha, USDA FS. “2 chicks hatched initially, only 1 survived to fledge, which isn’t uncommon in birds of prey.”

Visits to the nest did not reveal the exact cause of death of the 2nd chick, but climber cooperation with closures are crucial to the eagles.

“Golden eagle pairs are most susceptible to disturbance when choosing a nest. These closures allow the birds to pick the best site for survival without impact of other factors, such as human presence. Once chosen, nest sites stays closed until the eagles fledge in late July,” said DeNasha.

After the eagles’ site selection was made, unused areas opened in Apr.

The annual nesting closures include popular rock climbing spots at Eagle, Blob, Bitty Buttress, & Security.

Through 7/31/20, the closures protect a long-established golden eagle nesting territory. Happy Hour, Bihedral & Riviera remain open as long as visitors stay out of the closed areas.

It is against federal & state law to disturb any nesting bird of prey. Only employees, volunteers, & wildlife professionals under an agreement with the FS enter nesting areas for monitoring purposes. This is for the integrity of nest & the safety of the eagles, those conducting surveys, & the public. Visitors help protect wildlife by respecting all closures & leaving immediately if you should accidentally enter one.
