he remains of a Purépecha boat called a tepari and other ancient artifacts have been uncovered during a massive cleanup operation to help save Lake Pátzcuaro, in the state of Michoacán, from extinction.
The traditional canoe — which stands out for its considerable length of 14.8 meters (48.5 feet) — was found in the vicinity of the island of Janitzio, located in Lake Pátzcuaro, which has been inhabited by the Purépecha people for centuries.
Here is the link for more about that.

A magnet is one of the must-have tools for any detectorist. A magnet can be useful in a variety of ways. I often use a magnet to separate coins.
I haven't studied a lot of my foreign coin finds. After a quick inspection, I just put some of them aside for a later time.
At one time it wasn't as easy as to research foreign coins as it is now. I found a lot of foreign coins before the internet was so common, and before the internet you needed a coin book that covered the many different world coins. As a result, I put many foreign coin finds aside rather than taking the time to look them up.
I once used a magnet to separate a group of Canadian coins. I reported on that once before. The magnet quickly separated many of the Canadian coins from the older silver coins, which weren't attracted to the magnet. It was much quicker to separate them that way. I reported on how I did that in this post. The Treasure Beaches Report Direct From Florida's Treasure Coast.: 9/10/18 Report - Three Hurricanes Now In The Atlantic. Little to No T. C. Erosion. More Silver Coins Found by Using a Magnet.
If you have a bunch of US pennies, you can use a magnet to quickly pick out any steel cents. That is another example.
Tonight I decided to look through some German coin finds I hadn't really looked at very much before. Many German coins are ferrous, but some are aluminum, which do not stick to the magnet at all, and then there are some that are 75% copper and 25% nickel. So the iron coins are strongly attracted to the magnet. The copper/nickel coins were slightly attracted (they stuck but not nearly so strongly). And the aluminum coins did not stick at all.
Of course, coins from various countries will differ in composition and magnetic attraction but using a magnet can help you separate coins of many different types.
One caution: put a paper on the surface of the magnet so that coins attracted to the magnet will not be marked by the magnet when there is a strong attraction.
Below are three of the German that were easily separated by using the magnet.

Also use a magnet to check artifacts when you are not sure of the artifacts composition.

Like I said the other day it is the time of year to keep checking the National Hurricane Center map for tropical activity. There is one area out there now that is expected to develop, although it won't affect us.
