We beach hunters tend to toss the word erosion around rather loosely these days but the truth is that not all erosion is the same. Per example, if we see two foot of erosion over an area of beach and that remaining beach is still made up of several feet of deep fluffy sand then that erosion generally isn’t what we’re talking about unless it has invaded those generally dry dune areas, etc. What we are talking about is erosion that has left behind “firm bottoms”…bottoms that are firm enough to support items like dense gold rings, etc. So there is a significant difference in the types of erosion being sought. About the only time this may not be the case is during the height of the summer season when recent drops occur more frequently and even then these denser items sink pretty quickly.
Take a gold ring for example, it is very dense/heavy with little surface area to provide resistance, so unless it encounters something that will support its weight as it’s sinking then it’s generally going to keep right on sinking until it does. So think, “firmer bottoms,” as that is really what we’re after, these firmer bottoms either being dense enough to support the goodies we’re after or at the very least they’ll help to slow the sink rate of those denser items. Find these areas and you’ll likely start to encounter items like old fishing weights, rusty nuts & bolts, and this sort of thing. These are the areas we’re looking for.
If we could do a cutaway of the beaches we hunt we would discover that these firmer layers of beach don’t transcend along a lateral line but rather they appear much the same way as that little red line on a heart monitor that’s attached to someone with an irregular heartbeat. Find these spiked areas along the beaches you typically hunt and you’re far more likely to experience better consistent success there, especially when there is some erosion. And if these places are located behind those popular tourist locations and/or busier areas of beach then all the better. Two feet of erosion over six feet of deep fluffy sand doesn’t hold much promise, however, this same two feet of erosion leaving only a foot or two of soft sand, or less, above these firmer bottoms is quite a different story.
Cheers!….and as always, good luck and be safe out there!
