What is a pingo scar?
This article uses the phrase "pingo scar" about 5 or 6 times, without ever explaining what a pingo scar is. I tried looking in the article on pingos, but it never uses the word "scar" at all. Someone ought to write about that, and include some links. --50.199.149.121 (talk) 19:58, 20 August 2015 (UTC)
 * As explained in the reference, a pingo scar is a waterlogged hole left over from a former pingo. --Jakob (talk)  aka Jakec  20:35, 20 August 2015 (UTC)
