Mystery Solved: Bigfoot killed the Yosemite Sentinel Dome's Jeffrey Pine!

Famous Yosemite landmark withered by Sasquatch Pee. 

The YETI not SETI Institute unleashed a torrential stream of salty uncertainly this weekend, releasing quasi-scientific data which points to copious volumes of Bigfoot urine as the ultimate cause for the death of the famous Yosemite Sentinel Dome Jeffry Pine.

Recent Bigfoot sighting at the dead pine's resting place on Sentinel Dome.

"We have tons of pee proof", claimed Dr. Karl Blinng, Director of the legally fragile YETI not SETI Institute. "I only paid $3,000 for it. This data proves only a Sasquatch could have drowned that piss-poor plant!"

Sasquatches are known to cause environmental damage from excessive urination on Earth and Mars.

Speculation exists, as confirmed on authoritative major Space Alien History cable TV shows, that Sasquatch urine was also responsible for the premature malfunction of a Mars Rover. Sasquatch sightings in Yosemite National Park are quite common. Coincidental? We think not! "It's hard to tell the difference between the Bigfoots and many tourists during the high season", said one exhausted park ranger.
