0 someone who goes walking or climbing in underground caves:
A potholer was airlifted to hospital after falling almost 60ft inside a cave.
He is a potholer and in 1988 he volunteered his skills to rescue victims of a major earthquake.
Potholers delight in underground "lava tubes" up to seventeen miles long.
For example, with the rescue of potholers, and large-scale searches for a missing person.
Climbers, potholers, mountaineers—vast numbers of people are more interested in these sports.
Every weekend we hear of a potholer who is trapped somewhere.
The entrance is actually in the back garden of a private house but access is allowed for potholers.
The cave systems in the area are a strong attraction to cavers and potholers.
