Mount Burgess and Emerald Lake in Yoho National Park, British Columbia, Canada

Yoho National Park, British Columbia, Canada

Yoho sounds like something you'd shout from a mountaintop—and honestly, you might find yourself doing just that. Established in 1886, Yoho National Park in British Columbia is known for its towering cliffs, glacial lakes and thunderous waterfalls. It's the second oldest national park in Canada and part of the Canadian Rocky Mountain Parks World Heritage Site. Covering 131,300 hectares, the park is home to the Burgess Shale, a globally recognised fossil site. It consists of well-preserved marine life dating back over 500 million years—vital to understanding early evolution. Here, one can observe elk, mountain goat, marmot and the occasional grizzly bear in their natural habitat. Lodgepole pines dominate the forest canopy, while avalanche lilies appear shortly after snowmelt.

Featured in today's image is Emerald Lake. The lake's vivid colour comes from glacial silt—known as rock flour—that scatters green and blue wavelengths of light. It's ringed by forested slopes, avalanche paths and peaks like Mount Burgess. If you ever find yourself here, remember to pack a snack—this view might just make you walk the loop twice.
