AGS / Geology / General Geology / Fieldtrips

Geologists look at outcrops anywhere they are accessible and sometimes in places not so accessible. Every now and then we find outcrops so interesting that we cannot keep them to ourselves and as a result we create guidebooks to share with everyone! In our wanderings "in the field" we locate numerous rock spots along roads, trails, or streams. To see outcrops along roads view the Roadside Geology section below or to see outcrops along streams view the Geofloats section below.

Buffalo National River - Ponca Lower Water Bridge to Kyle's Landing
by John David McFarland

The geofloat trip on the upper Buffalo River puts in at the Ponca low-water bridge and ends at Kyles Landing, a distance of about 10.5 river miles. The geofloat guide file is in .pdf format so you will need to have a current version of Adobe Acrobat Reader® for the download. The file size is approximately 1 Mb. Presented separately is the geologic map for the geofloat. The geofloat trip guide and geofloat map compliment each other. Therefore, both should be downloaded. A separate file entitled Ponca area topography presents a 3 dimensional block diagram of the regional topography with some local features labeled.
