Skating Backcountry Lakes and How I Determine If Ice is “Safe” to Skate.

My adventure to round top lake where I teach about some ice safety. This lake has been on my list for ages and I finally got to skate it!! Here are some guidelines for determining the safety of freshwater ice. The following table of safe loads is valid ONLY for ice that is clear and sound, with no flowing water underneath. it is not reliable for stationary loads. When in doubt, stay off the ice. Not all ice will be the same thickness in all areas! It is highly recommended that you familiarize yourself with the Safety on Floating Ice Sheets information by CRREL. Loads on Ice Required Minimum Ice Thickness in inches Description of Safe Moving Load 1-3/4 One person on skies 2 One person on foot or skates 3 One snowmobile 3 A group of people walking single file 7 A single passenger automobile 8 A 2-1/2 ton truck 9 A 3-1/2 ton truck 10 A 7 to 8 ton truck These are based on a dynamic load not static. So after knowing this information I came to the conclusion that 4 inches was quite an added safety factor. This allows for variables in ice thickness and quality.
