Analysis of the permit process will resume tomorrow due to the following news.


     Yosemite National Park today released photos of an unprecedented geologic occurrence. The signature landmark of the famous park, Half Dome, apparently split along a persistent “dike” that geologists have been monitoring for years. The pre-dawn event surprised park authorities and visitors alike. A dull thud sound was reported by campers in the nearby Upper Pines campground. Geologist Mark Mywerds said the recent heavy snows and sub-freezing temperatures continued a long known pattern of exfoliation as expanding frozen water gradually pushed apart the rock along a vein of delouvian granitic.  Columnar jointing in the area of schlirien extrusions often occur  near pegamitie diotite.  This was a textbook example said Mywerds. This pressure finally ruptured the large monolith.  Remnant talus now fills Mirror Lake. Click to enlarge.

     Park officials confirmed that the south facing slope of Half Dome was probably kept intact by the support provided by the 92-year old steel cables that are enjoyed by thousands who summit the rock each year. The cables provided the compressive vectors to keep the rock intact as shown above. The irony of the distribution of permits to hikers of Half Dome on the same day as the rupture amazed officials. Since the rock was confirmed as “stable – level G4” at press time, Department of Interior spokesman Ranger Abril Phul said that the National Park Service has directed that Half Dome be removed from its “Wilderness” designation and free ascents without any controls will resume when the cables are erected later this spring.

Unrelated thought worth quoting: “He who laughs last, laughs after everyone else has finished.” – A wise old man.

    I knew that compressive vectoring would come in handy one day.

    I hear the marmots ate through the wires on the elevator between the Sub Dome and the Visor too.
