Hickory Hills Paha
As I was doing the research for the earthcache, I found that all info was from the original earth cache was the best way to describe the cache, which was by
Located within Hickory Hills Park, Casey's Paha State Preserve is home to a very unusual geologic feature: a paha. Access can be gained off county road V-37 (Dysart Rd), just 1.75 miles south of the Black Hawk/Tama County line. Park is open from 6am to 10:30pm year-round.
Paha is a Dakota Indian word meaning "hill" or "ridge". It was first used in 1891 by geologist W.J. McGee to describe elongated hills, capped with windblown silt (loess) and sand in northeastern Iowa. Paha are isolated, northwest-to-southeast oriented ridges, which rise above the surrounding plain. These landforms are characteristic of the southern portion of a major landform region know as the Iowa Erosion Surface. Research drilling on this paha in the 1960's was instrumental in establishing that these features are erosional remnants of a higher, once-continuous glacial plain.
The deposits beneath the loess in paha are all that remain of these old glacial materials, which are still widespread in southern Iowa. Paha soils indicate that forests, first coniferous then deciduous, were the native vegetation for several thousand years prior to settlement. These prominences were wooded islands in a sea of prairie grasslands. Perched water tables, common on paha, may have helped the woodlands survive in these locations. The trees, in turn, may have had some effect on trapping the 30,000 to 17,000 year-old, wind-borne silt and sand that cap the paha. Casey's Paha is also the "type locality", a standard geological field reference, for the Hickory Hills Till, the approximately 500,000-year-old glacial deposit that forms mosat of the paha's interior.
The 55-acre Casey's Lake is one of the state's premiere large-mouth bass hot spots, and camping is available too. There are several miles of hiking trails which showcase the paha and a large variety of native plant and animal life, as well as a wildlife exhibit which includes deer (including several albino deer), elk, and bison to name just a few. So, come enjoy the paha and make a whole day/weekend out of the experience.
1 From the waypoint you are standing at can you tell the height of the surrounding hills to the south. “If you have a gps like Colorado with Topo maps you tell how height the hills are.” But if you don’t have a GPs like that you can give your best guess. The waypoint is at 862 feet.
2 You know the there is old glacial materials under the hill can you tell what kind they are?
3 Now got to Waypoint # 2 N42 16.012 W92 18.839 This the sign and tell me what the firsot two sentences say.
4 At waypoint #1 you will need your photo with GPS in hand with hills to the south in the Photo!
