BANFF – The Bow Valley Naturalists are launching its 2020 speaker series with an informative talk that will dive into the fascinating story about the changing colour of alpine lakes in the Rocky Mountains. 

The husband and wife research team of Janet Fischer and Mark Olson will present their findings from studying the ecology of mountain lakes over the past 13 years.

With the help of their undergraduate students and their two children, Fischer and Olson have worked to systematically document a unique long-term data set for lakes in Yoho and Banff national parks. 

Their research aims to better understand the dramatic changes in colour between alpine lakes that have been detected over the short and long term. Whether it is from rain events or melting glaciers and changing seasons, and the effects of these changes on plankton that live in these lakes – the next Bow Valley Naturalists event will share their findings.

This free talk takes place Tuesday, Jan. 28 at 7:30 p.m. at the Banff Seniors Centre.
