2 Best Sights in Yoho National Park, British Columbia

Recognized as a UNESCO World Heritage Site and part of the larger Canadian Rocky Mountain Parks World Heritage Site, this layer of rock deposits contains amazingly well-preserved fossil specimens that have visible details from the creatures that existed in an underwater ecosystem over 505 million years ago. The Mount Stephen trilobite beds were discovered in 1886 after a railway worker reported finding stone "bugs" in the talus. Paleontologist Charles Walcott from the Smithsonian Institute visited Mt. Field in 1909, where he opened a quarry and started collecting and analyzing specimens.

Spanning the Kicking Horse River, this natural rock formation was created when the hard limestone eroded more quickly than the softer rock causing cracks to widen until the flow of water changed and formed a bridge. A short pathway displays interpretive signage explaining the erosion process as you walk to several lookouts that provide views of the geological formation from different vantage points.
