I remember a time (~1998-1999) when the following terms were used: 500' prominence is a hill 1000' is a mountain 2000' is a major mountain 5000' is an...

Hill seems like a misnomer as it implies a rounded uneventful heap of dirt. There are many sub-p1000s that are far more challenging than any contiguous US...

Or perhaps, Ken, the "electrum" could be the designation for P1000 m summits - a cutoff value that is closer to the geometric mean of 600 and 1500 meters. ...
