Two immature butternuts harvested (vines dead); one immature butternut still on vine

I wonder if these two harvested immature squash will ripen. One is well on the way but definitely not there yet; the other is very green with just a touch of tan at the stem.

Harvested the one butternut

The stem is still green, but the body is nice tan and I worried about something eating it if left out much longer.  It's very nice, same size as my one remaining butternut from last year.  Quite the mystery why only this one single winter squash took.  So far it appears none of the others have taken, even though quite a few have been flowering.  Well, there is one butternut that put on some initial growth, but it seems to have stalled out. Maybe it will just be a small butternut.
