A carrot harvested but it was small and forked

From the west-most third of the carrot bed, so might have been a Nantes unless it was one of the Boleros that I used to fill gaps throughout the bed.  The top at the soil looked like a nice size, so it was disappointing to see it was only a couple of inches and forked.  Tasted ok though.

The carrot greens are over 18" high, but I'll still wait before harvesting more.
