The cache is a regular lock-and-lock hidden just off the Three Lakes Trail. Clarence Fahnestock State Park was once a hotbed of mining activity. The Three Lakes Trail near the Route 301 end follows one of the seams of magnetite which was the primary ore being mined. If you pick up the Three Lakes Trail at Route 301 — for which the parking and trailhead coordinates are provided, you will see on both sides of the trail extensive evidence of past mining activity. Close to the cache, the trail actually crosses (thus the cache name) an “adit” — a horizontal entrance to a mine — that runs from east to west then turns sharply north, parallel to the trail. The cache is located a short way into the adit on the west side (right, if coming from Route 301) of the trail. You may find a trail map at https://parks.ny.gov/parks/attachments/ClarenceFahnestockTrailMap.pdf Insect repellent is highly recommended during the summer season.
