In this series of Side Image and Down Image scans I’m scanning an original creek channel in the back of Bear Creek on Pickwick Lake. While scanning I found an interesting object on the lake bottom.
This one will be of Objects Found.
Take a look at this side scan and see what you can find before looking at the photo below. As I showed you in the last Blog on Bottom Composition you can see the darker colors are a soft bottom in this case the original creek channel. And the brighter color is of the harder bottom composition. The shadows next to the objects lets you determine the height of the object on the lake bottom.
Photo 2 below…….
Now that you’ve had a chance to find the objects I’ll point out what you should have found. (1) is a false return as I was making a sharp turn with my boat so disregard it. (2) is a sunken tree top that either was placed there by another fisherman or washed into the creek and sank on its on. (3) is a very large stump that you can tell by the shadow it casts. (4) Finally as you can tell this is an old sunken boat. It looks to be a flat bottom boat without an outboard engine attached. The GPS coordinates of the area if you want to look at the objects to learn your unit is as follows.
GPS: N 34 48.113 – W088 05.365
Hope this helps you understand units.
