The Grand and Rogue River Confluence

This is a Earth Cache. Just had to go to the destination they pointed out and take a picture of yourself there.
This was the 1st of five we did today.

Here is the information they supplied on it: Pretty interesting!
River - A large natural stream of water emptying into an ocean, lake, or other body of water and usually fed along its course by converging tributaries.

Tributary - a stream or river which flows into a larger stream or river.

Confluence - The meeting of two or more bodies of water. It can be where a river meets a lake, sea, or ocean. Or in our case here, the junction point of a river and its tributary.

The Grand and Rogue River Confluence

Down river, 150 yards or so to the right from where you stand, the Rogue River enters the Grand River. This spot where the two rivers join together is called a confluence.

From here the mouth of the Rogue River may be hard to see at times because the Rogue is a much smaller river. But the contribution of its waters and their effect on the Grand River are unmistakable.

The Rogue River is 42 miles long and has 234 square miles of watershed. It varies from 15 feet wide in the upper sections to 80 feet wide near its end and is between 1 - 4 feet deep. There is one dam along its length- the Rockford dam.

The Grand River is Michigan’s longest river and has 8,592 square miles of watershed. Its headwaters are in Somerset Township, Hillsdale County and it flows into Lake Michigan approximately 260 miles downstream at Grand Haven. It has numerous dams along its length. Its major tributaries are the Red Cedar River, Looking Glass River, Maple River, Flat River, Thornapple River, and the Rogue River.

Early in our country's history both the Rogue River and the Grand were used as an important transportation routes by Indians, explorers, traders, and finally white settlers. During Michigan's lumber era in the late 1800s their waters floated timber to the mills along the shores of the Grand River. Today their uses are mainly recreational.

Logging Requirements

To log this cache you will need to complete the following. All that should be posted with your log will be a photo. The answers should be e-mailed to us and not posted in your log. Go ahead and log your find at the same time you're sending your email answers.

* Post a picture of yourself/team with the Grand River in the background.
(alternately: if you do not have a digital camera - include with your email the answer to this question - what is located at the posted coordinates?

Many times at a confluence the tributary will have a dramatic effect on the course and width of the river it is entering. Email us the answers to the following questions which can be found by observing the rivers from the posted coordinates.

1. Describe what happens at the confluence of the Rogue River and the Grand River. Is there any change in the course of the Grand River?

2. Is there any change in the width of the Grand River after the confluence?



I don't know if you can see it but there is a huge crane on the tree out there.


This is what we had to take a picture with..
Paige was scared she was going to fall in. I told her to hell with fallen in worry about what will come out of the water and snatch you off the dock..lol She hated me after that.
