How Geocaching Works

This cache is placed along the newly created trail that passes through Thomas Park.
**PLEASE OBSERVE PARK HOURS OF 6AM TO 10:30PM**
Log jams alter flow hydraulics, which control characteristics of scour and deposition. Thus, log jams become an important factor in the geomorphology of wooded streams and rivers.
Water is often impounded on the upstream side of a log jam, creating a pool. Water draining from this pool often creates a downstream "plunge pool". Decrease in water velocity in the pool often results in deposition of sand or gravel in the pool bottom. This may progress into "bar" formation.
Log jams also cause shifts in stream flow. They often redirect flow into former channels or spur creation of new channels.
