Geocache Description:


Hartman Reserve Nature Center Gorge

 

This Earth cachr is in Hartman Reserve Nature Center North Unit


 Hartman Reserve Nature Centeris a 300 acre wooded isle located in the heart of metropolitan Black Hawk County. Hartman lies in the center of the Waterloo, Cedar Falls area. It offers many activities and experiences to all its visitors. Hartman Reserve Nature Center is an entity of the Black Hawk County Conservation Board. Since our creation in 1976, Hartman Reserve Nature Center has been designated as an Iowa Watch able Wildlife Siteand an Important Bird Area. Deer, otter turkeys, pileated woodpeckers, red-shouldered hawks, foxes, vultures, and bald eagles are some of the wildlife you might see. 

 

 

 Gravity Flow erosion! As you enter the site you wiil see Gravity Flow ersion all over as you go down to the posted coordinates. 

 

 

 Mass Movementis the down slope movement of rock and sediments, mainly due to the force of gravity. Mass Movement is an important part of the erosional process, as it moves material from higher elevations to lower elevations where other eroding agents such as streams and glaciers can then pick up the material and move it to even lower elevations. Mass-Movement processes are always occurring continuously on all slopes; some mass-movement processes act very slowly; others occur very suddenly, often with disastrous results. Any perceptible down-slope movement of rock or sediment is often referred to in general terms as a landslide. However, landslides can be classified in a much more detailed way that reflects the mechanisms responsible for the movement and the velocity at which the movement occurs. One of the visible topographical manifestations of a very slow form of such activity is a scree slope.

Slumpinghappens on steep hillsides, occurring along distinct fracture zones, often within materials like clay that, once released, may move quite rapidly downhill. They will often show a spoon-shaped isostatic depression, in which the material has begun to slide downhill. In some cases, the slump is caused by water beneath the slope weakening it. In many cases it is simply the result of poor engineering along highways where it is a regular occurrence.

Surface creep is the slow movement of soil and rock debris by gravity which is usually not perceptible except through extended observation. However, the term can also describe the rolling of dislodged soil particles 0.5 to 1.0 mm in diameter by wind along the soil surface. 

 

 

 In an e-mail to me:

1.Tell me the width and depth and how long the gorge is!
2. Describe to me the surface at the bottom of the Gorge looks like. (You see Rocks, downed tree’s, etc.)
3. Based on what you might know already, or what I have described in this Earth cache’s write up, how can the gorge have influenced the area?

     And

     4.When you log this cache, please upload a picture of yourself/team with your GPS clearly visible at the near the posted coordinates at the bottom of the gorge. Bottom Deck would the best. Do not hurt the surrounding area!  

     Special Thanks to ED Gruenwald director of Hartman Reserve Nature Center for allowing me to place this earthcache.
