There is not a physical container to find here as this is an EarthCache. I'll provide some geological information as a learning exercise and you'll have a chance to show what you learn and apply it to this location! To validate your log, please complete these logging requirements.
Logging Requirements
From this EarthCache site, you are standing above an outer curve of the Bear River. Read throught the information I provide below and take a look at the river and the surrounding areas. To validate your log, please send me the answers to these questions:
1. Take a look at the bank below where you're standing and compare it to the bank across the river. Note the slope of the bank on each side of the river. What evidence at the site do you see to that confirms that you are standing above an outer curve or cut bank?
2. Take a photo of you or a geocaching item at the site, without revealing any answers. This can be sent or posted in your "Found It" log.
Background
The Bear River begins in the Uinta Mountains in Eastern Utah. It flows north through Wyoming and Idaho then meanders back south through northern Utah before finally emptying into the Great Salt Lake. The river spans "about 350 miles and is the longest river in North America that does not empty into the ocean". (Source: https://bearriverheritage.com/explore-the-bear-river-basin/)

Basics of River Flow
This picture shows a stream channel with three meander curves:

The dark blue line is the thalweg. The thalweg is the fastest and deepest flow of water in a river. When water flows through a straight section of river, the thalweg generally flows down the center. On a curve, the thalweg shifts toward the outside of the bend.
Cut banks, which are steep banks on river curves, are formed because the fast moving water on the outside of the bend erodes and carries away rocks, dirt, and other sediment. This can cause the bank to become steep and unstable. Cut banks can sometimes form a nearly vertical cliff. During periods of high rainfall and high water levels, cut banks can be especially unstable. This can cause mass wasting - which is the movement of rock and soil down a slope (including debris flows and landslides).

In contrast to the outer curve, the water on the inside of the river curve moves more slowly. The slower water drops or deposits the sediment it picked up when moving faster. This process forms a gentle slope on the inside curve called a point bar. The point bar is usually crescent shaped and composed of deposited sand or gravel.
The combined processes of erosion on the outside curve and deposition on the inside curve cause the river's curves to become more exaggerated over time. Steep cut banks can be a suitable habitat for birds, like kingfishers or bank swallows, which burrow into the loose soil to nest.

The cut bank geology of the Bear River isn't especially unique but it is historically significant! In fall 1866, a group of Scandinavian immigrants came to the Bear River area to settle. For their first year in the valley, they lived in dugouts built into the west banks of the Bear River just north of this site! The dugouts had roofs made of poles, willow branches, straw, and dirt. In fall 1867, the settlers moved from the dugouts to a log and adobe fort for protection.
