I seen a movie a while back it had a guy who was a tracker and he was going to go look for something and was taking a scientist with them a women the found a hidden indian viiliage through a cave and after a while he needed to blow it with dynamite so no one else could find them and try to harm their villiage and ends up dying. One specific part in the movie that I remember is one of the indians grabbed a stick of dynamite and he took it from him and showed them that it was bad by rubbing his finger one the sweat of the dynamite and through it and the sweat blew up. I would appreciate help finding this movie.

This one might be The Last of the Dogmen (http://www.imdb.com/title/tt0113617/) from 1995, starring Tom Berenger, Barbara Hershey, and Kurtwood Smith, with a narration by Wilford Brimley.
