After you've zoomed in on the cove, creek, or flat you want to check out, click on the date indicator at the bottom left corner of the map. A drag bar will then appear on the top left corner of the map. As you drag along the timeline you'll notice there are several images of the same location from past dates. By utilizing this feature regularly, an angler could quite often see what the area looks like during different seasons, different water levels and even more finite features like aquatic vegetation cycles. This is especially valuable if the lake gets really low or high only once every few years, and you anticipate one of these scenarios occurring during your visit. In essence, it's the measure of an area's past, present and potential future.
