I’ve wanted to find these 10 Firefighter Caches on the Kiel River for some time and decided to pull the trigger today. It was a brisk 8° with a small breeze when I hit the frozen river this morning. Fresh snowmobile tracks from last night assured me it would be safe & great for walking. Faint geotracks from all the activity from last week also helped. It took a little effort to open this frozen cache container and signed the log. This is an awesome series and thank you 4mnms for all your efforts in putting this series together.
