A senior research scientist with a doctorate from the University of Wyoming will speak Feb. 13 at the Roaring Fork Conservancy’s River Center on “Anchor Ice in Mountain Rivers.”

The talk by Edward Kempema runs from 6 p.m.-7 p.m. It’s preceded by light refreshments, according to information from the RFC. The talk is free but seating is limited. RSVP to reserve a seat by going to roaringfork.org.

After his presentation there will be time to chat with Kempema, according to the schedule.

According to the program description, “Anchor ice forms underwater and attaches to the beds of rivers, lakes and seas in cold regions. It is a fascinating and poorly understood phenomenon.”

Kempema has studied ice for 40 years. “He will discuss the conditions leading to anchor ice formation, distribution in small mountain rivers and impacts on mountain river systems – including winter flooding – and what potential management practices are available,” according to the program.
