Sorry to say but it looks like the board is a Sintered base. So permanent repair with ptex is a no go
Sintered bases are made from Ptex and more likely to to be successfully repaired (w/ptex) and welded. Sintered bases are also less prone to damage
Extruded bases- are also made from ptex and can be repaired and welded, the extruusion process makes it more difficult for them to be repaied. Extruded bases are more easily damaged due to the softer nature.
OP- it looks like you rode over rocks, or other jumk under the snow. If the core isn't eposed don't worry to much (you can razor off any hangers) and just get your board repaired at the end of the season. You'll get a lot more dings and scratches before this one is over. If the core is exposed do ptex the base (do it your self if your confident, or have a shop do it).
