I'm seeing a lot of ECTX results reported lately and I'm wondering if they are actually cases with no fracture (see p 39 of SWAG) ? In the several thousand ECTs that I've looked at or done myself, it's rare to see an ECTX in snow with some cold content (i.e. winter snow). You can get an ECTX in the spring when you've got a really strong block. I suggest that a lot of these ECTXs are actually ECTNs with thin fractures that don't extend past the shovel width. End of nitpicking.
