More rockfalls and a “minor collapse”
From our friends in the green jeans:
Due to a minor collapse in the pedestrian tunnel at Hetch Hetchy, the trail to Wapama and Tueealala Falls is inaccessible at this time. NPS and City of San Francisco staff will be evaluating the situation on Monday.
Due to continuing rockfalls from Middle Brother, Northside Drive between Camp 4 and El Capitan crossover in Yosemite Valley remains closed. Please be aware that this closure includes both vehicular and pedestrian traffic. The area was
closed following a rockfall on December 18, 2007 that sent one large boulder and several smaller rock fragments onto the road. Since that time, there have been at least four additional rockfalls from Middle Brother, with the most recent event
occurring at 10:16 am on January 8. This most recent rockfall sent additional rock debris onto the road. The rockfalls are originating from an area that was last active in March 2000. Winter storm activity has complicated hazard assessment, but
the park is closely monitoring rockfall activity.
