"A crevasse nursery" ?

I am studying crevasse formation. I am looking for a nice shorthand i can use for places where crevasses are just cracking open. Not really convinced by my theasurus lookup.

@agrinsted I kind of like "hatchery", tbh.
@iamdonovan Thank you. Probably the best of those options. Maybe I will try it out and judge if it is sufficiently self-explanatory. It'd be nice if figures etc can be read without cross referencing to the text too much.
