Someone on the Glacier Hiking and Backpacking FB group posted that they camped at GLF and ELF last week, and 2 of the campsites at ELF were still snowed in. That probably explains why ELF is still in winter status.COS,ELH,GAB (curious ELH but not ELF)
Well, I'm answering my own question. Last night a friend notified me that the site I was looking for opened up for the day I needed it. So I quickly got online and modified my permit to added it on the last night. I had no problems.
