Does this aircraft not have a radar altimeter?
The undulating terrain at KBMH would make any use of RA problematic. Recall that the
Polish presidential Tu-154 that crashed in Russia 10 Apr. 2010 was using RA, which misled the crew as they approached over a ravine.
In that case, the ravine was below the airfield elevation; at KBMH the ravine (or other low terrain) was below the intevening hill.
