First time this year:
Boltinghouse Hill is the one in the middle. It is exactly .25 miles with 181ft rise (measured by Garmin, confirmed by MapMyRide). The first half averaged about 18%, followed by about 50 feet at 3% to 10%, and the last half averages 18% peaking at 23%.
Everytime a do this hill, I feel younger and stronger!
