“They found gold in a crevice at the mouth of the first Stream above Bear, and named it, in consequence, Crevice Gulch. Hubbel went ahead the next day for a hunt, and upon his return he was asked what kind of a stream the next creek was. ‘It’s a hell roarer,’ was his reply, and Hell Roaring is its name to this day. The second day after this, he was again ahead, and, the same question being asked him, he said: “‘Twas but a slough.” When the party came to it, they found a rushing torrent, and, in crossing, a pack horse and his load were swept away, but the name of Slough Creek remains.”—Topping.
