One of my favorite vacation spots is the Jackson Lake Lodge in Jackson Hole Wyoming. It is a very historic place and has the best breakfast buffets in the world. I know I'm going to sound like an advertisement, but it is just because I enjoy the place as much as any I've ever visited, and this week, like every year around this time, it is where the world banking conference will meet, so you'll probably being hearing something about it on TV - definitely on the business shows.
Above is the restaurant and below is the lobby, both of which looks out on the Grand Teton Range. People gather in the lobby and enjoy watching the changing light on the Tetons after a day of hiking. You can see some artifacts in the display case (below) and more artifacts in the bar just to the right of the lobby.

Jackson Lake Lodge |
During the summer of 1926, John D. Rockefeller, Jr. and his family spent several days touring Jackson Hole with Yellowstone National Park Superintendent Horace Albright. Albright arranged the tour to inspire Rockefeller to preserve land along the base of the Teton Range. Albright showed the Rockefellers how telephone lines, billboards, a dilapidated dancehall and uncontrolled development spoiled the majestic views.
The party hiked up Lunch Tree Hill for a picnic, enjoying an unobstructed view of the Teton Range. After the tour, Rockefeller and Albright launched a plan to purchase Jackson Hole land and set aside this exquisite landscape for future generations. Visit the hill today to view the panoramic vista of Jackson Lake and the Teton Range.
... Over the next five years until the Lodge was opened, the town of Moran was removed from the landscape and moved about 11 miles to the west. The remaining land was regraded and re-vegetated, removing all traces of its former location. The “ramshackle” town was an eyesore in the planned view shed planned for the new Lodge. Many of the original cabins built by Sheffield were moved to Colter Bay, and those that were in rough shape were burned.
Actually, some signs of the old town remain. For example, you'll see glass and porcelain shards along the path at the top of Lunch Tree Hill, which is a short walking distance from the lodge deck. You'll find an area like that near many mountain hotels or lodges.
The Jackson Lake Lodge rooms are not luxurious or fancy, but that is not what I look for anyhow.
You can raft down the Snake River, as I've talked about before, or take a day tour to nearby Yellowstone. The lodge will soon be closing for the season.
The last time I was there, the cold was settling in and the lodge was scheduled to shut down in a few days, and I went out late one night to see the crystal, clear sky while the coyotes were howling. I fondly remember before door closed behind me, a mouse scurried in and ran around behind the reception desk. Maybe he planned to stay safe inside for the winter.
Anyhow, a great place to visit even though you aren't allowed to detect in the park.

Gridding: Myths and Value.
It seemed that decades ago, I read a lot about gridding. It seemed to be the big thing. I don't read or hear about it so much anymore. But that might be because I don't read the same kinds of magazines, which might have something to do with that, but the point I want to make today, is that gridding was not everything it was cracked up to be.
People talked about thoroughly covering the area, but didn't always realize how much was missed. First of all, it is unlikely that anybody covers every inch despite what they think - even with overlapping and being very careful.
Secondly, when coverage is considered, you are not attempting to cover a square or rectangular area. There is another more important dimension - depth. Even when depth is considered, the assumption is now that a cubic area is being covered. The problem is that detection depth varies from area to area - sometimes very quickly due to things like changes in ground mineralization. On a saltwater beach, especially in the low tide area, water is coming and going changing salt mineralization, not to mention other variations such as black sand, dug holes, etc. etc.
We must consider a lot of variables, including our own behavior. We aren't machines the coil doesn't move in straight equally spaced lines. The coil speed varies throughout the sweep coming to a halt at the end of each sweep with the abrupt change in direction. And the coil height also varies. Most people tend to raise the coil near the end of the sweep. The effects are subtle if you are very careful, but even then, the ground level changes, both gradually, sloping towards the water, for example, or suddenly where there are holes or other irregularities. The point of that is that a variety of factors result in coverage that is irregular and inconsistent, at best, no matter how hard you try to cover it all.
I learned early on that I was missing more than I thought even when I had a small area to cover. It was early in my metal detecting days, when a fellow at Hollywood Beach asked me if the metal detector really worked. He buried his watch while I didn't look and then I searched for it. I went over the watch and missed it. I was very surprised and wondered why or how I missed it. Now I know much more. It could have been I thought my search was tighter than it actually was. Now I know that the composition of the watch, how the watch was laying, and the settings on my detector could have had something to do with it. Even the direction of my sweep speed relative to the watch. But I learned that I was missing more than I thought. Since then I've learned a lot, but I still miss things. Even if you could thoroughly cover a defined area, you would still miss a lot to the north, south, east and west and below that defined area, but you are also missing things within the area.
The objects in the ground provide another obstacle. There can be target masking, targets in stealth positions, such as coins standing on end at depth, disruptions in the soil matrix caused by holes or other things. The direction of your sweeping coil can miss an object if it is position in a stealthy position. I could go on, but I think that is enough to suggest that gridding does not necessarily provide perfect coverage even when done carefully. Instead of detecting a cube, the covered area probably looks more like a block of Swiss cheese. There are a lot of holes in it.
So, what is the remedy?
First, make sure that you really want to commit so much time and effort to the area as opposed to any other possibilities. To help you make that decision, I recommend sampling that area as well as some other areas.
Second, after deciding to focus your efforts on a limited area, be aware of the obstacles to complete coverage. Of course, you don't necessarily want to pick up everything, but that is another topic.
Be aware of the tradeoffs. Define what you most want to detect and what you are willing to miss and set up the metal detector and control your coil for best results.
Collect information as you go. Don't finish just because you started. Adjust. As you assess your finds and what you see, consider the new information, adjust. You might want to redefine your area of concentration. It might not be a square or rectangular area anymore. It all depends upon what you see and how you interpret the information you are collecting.
There are many other relevant topics I could continue with here, but I'll stop now.

You can see we now have a tropical storm Dolly in the Atlantic. It seems headed in our direction but is predicted to fizzle before reaching us.
The surf charts are predicted nothing more than about a two-foot for the next week along the Treasure Coast.
Good hunting,
