The Kicking Horse River, a Canadian Heritage river, originates in the Wapta and Waputik icefields in the park. This river has created a natural bridge through solid rock. This formation is located 3 km west of Field, accessible from the road to Emerald Lake.
The Canadian Rockies consist of sedimentary rock, with numerous fossil deposits. In particular, the Burgess Shale, located in Yoho National Park, has among the world's richest deposits of rare fossils. The Burgess Shale was discovered in 1909 by Charles Doolittle Walcott. In the southeastern corner of the park is an igneous intrusion known as the Ice River Complex containing deposits of sodalite, an ornamental stone.
