Study Says Half Dome Permit System In Yosemite National Park
Apparently Does Not Enhance Overall Hiker Safety.
"
The monitoring report noted that an "unimpeded visitor travel" threshold of just 30 people at any one time on the cables leading up the dome's shoulder was exceeded 15 percent on weekends under the permit system, but that on weekdays when permits were not required that limit was surpassed 65 percent of the time.
A higher "threshold," of 70 people on the cables at any one time, a number "when visitors perceive safety issues and unacceptable experiential conditions," was not exceeded on sampled weekend days, but was surpassed almost a quarter of the time on weekdays, the report added."
