So I got out my skis and was briefly inspecting them when I found two raised lines or creases on one of the skis. See pics below. I am not sure whether it is just the topsheet or the wood core that has cracked. When I flex it I don't hear the core creaking or cracking or anything.
Has anyone found anything like this or know what it is?
The creases are in the lighted part of the pictures.
