Yoho National Park, British Columbia, Canada - Emerald Lake

Yoho National Park forms part of the vast (23,069 km²) Canadian Rocky Mountain Parks World Heritage Area, as does the adjoining Banff National Park . Emerald Lake, famous for its turquoise water, lies at an elevation of 1300 metres. The forest around the lake is mainly composed of Picea glauca × engelmannii (white × Engelmann spruce), Abies lasiocarpa (subalpine fir) and Pinus contorta var. latifolia (lodgepole pine). Recent mountain pine beetle ( Dendroctonus ponderosae ) outbreaks have devastated Pinus contorta , most of which are now dead. Around the lake there are also small patches of “Inland Rainforest” containing e.g. Thuja plicata (western redcedar). Tree species diversity is low and most species are easy to identify.
