How Geocaching Works

Please note Use of services is subject to the terms and conditions in our disclaimer.

Geocache Description:

This should be a family friendly, educational earthcache. It's located to a busy road though, so watch the kids closely. You should be able to answer all questions from the posted coordinates. Be sure to read all the below information!

Use the information below to answer these questions about this earthcache. When you feel you have all questions covered, email me via my profile and I will ok the answers. Any "found it" logs will be deleted without answers to the logging requirements.

1) With knowledge of how creeks are formed and erosion of sedimentary rock, what type of materials are present on the creek bed? (If the creek has water running through it, what type of materials do you think is in the creek bed based on the eroded layers on the side of the creek?)

2) Does the creek bed appear softer or harder? As described below in the "Formation of a creek" heading.

3) Through knowledge of the climates effect on erosion, normal erosion rates and the sediment that lies on the creek bed, do you think the creek formed slowly or at a more rapid rate?

4) Although pictures can not be used as a logging requirement, they are still welcome. So take a pic or two if you want!

Formation of a creek:
Areas through which water can flow become eroded over time by that water, creating deeper and deeper channels. If the soil and rock is easily eroded this can occur very quickly. If the underlying material is very hard, it takes longer but still happens. The result is a river valley. Sometimes valleys are called ravines although ravines are usually either very shallow creek valleys or very short cuts in a slope, not long, winding creek paths.

Sediment and erosion layers:
Because creeks have eroded through layers of soil and rock, they expose layers that are not visible elsewhere. Visit the creek and look closely to see what the material in the bottom is like. It may be fine sand, silt or sticky clay. Some local creeks bottoms are quite flat and hard where the surfaces of sedimentary rock layers are exposed. This all caused by the formation of the creek.

Climates effect on erosion rate:
Creeks are as subject to climatic effects as the land around them, but not in the same way. When there is a great deal of rain, creeks swell and run more quickly, increasing the rate of erosion and deposits of sediments on the creek bed. In times of low rainfall, some smaller creeks can dry up completely becoming dry creek beds for short periods of time, decreasing the rate erosion. This creek can be both flowing or dry depending on the time of year you visit the cache.

Website Resorces:

Feel free to dip your trackables. Just don't drop them as there is no physical container for this type of geocache.

As long as you're here you might want to pick up the nearby trad-cache (visit link) and the benchmark that is on the bridge sidewalk, which is also nearby.
