Difficulty Classification: 2-3

Material:  Blue Agates of many shades with varying clarity and inclusions.

Terrain:  Tower Hill is one of several basalt ridges near Monroe.  Joints and vesicles in the country rock have been filled with agate and jasper in many places, and are often accessible for collecting.  The Tower Hill area is a state park which has granted Mineral Council clubs permission to collect.   We will be visiting 3 areas within this site:

1.       Tower Hill Trail.  The trail is actually a service road that has been closed to car traffic by the state.  It now serves as a path through the park, and is in excellent condition for hiking.  The road bed has been filled with material from nearby Cadman Quarry and supplemented by crushed rock from small quarry near the end of the trail; both of which are rich in blue agate. Most of the best material will be right under our feet during the day.

2.      Tower Hill Quarry.  At about 2 miles from the parking area is the local quarry, and smaller pieces of agate are common.  The largest vein runs right underneath an enormous pile of crushed rock.  If some of this can be moved, there may be treasures below.  Also here is a hidden seam that will take some hiking through the forest for interested adventurers.

3.      Hard Rock Work.  There are small but beautiful veins of nearly clear agate in a small knoll about 1 mile from the parking area.  The rock is very hard here and will require chisels and heavy crack hammers for those interested.

It is critical that every person on this trip has their own two way GMRS radio.  These are common and available at Costco, Home Depot, Walmart and Target.  

The Tower Hill Parking lot can accommodate only 4 vehicles, there are no places along the road to park.  Therefore, we’ll need to stage in Monroe and carry everyone in the group in 4 vehicles.  Please drive the largest car/truck you can.   A Discover Pass is required at the parking lot.
