There is a $1.50 fee per person to enter the state park. Park in the Sulpher Springs Trail picnic area.
The cache is hidden in downed trees across the stream from the main trail, below the Mountain Lake Dam. The cache is a clear plastic 2.8 quart cylinder with lid, and contains disposable camera, logbook, instructions, all not to be removed. Prizes which may be taken include 2 Hot Wheels cars, 1 egg of Silly Putty, 1 thermometer/compass key chain, 1 disposabe flashlight, and 2 yo-yos.
This is copperhead country, so be careful of snakes.
My thanks to KlownKlan for resurrecting this site. :-)
