Hi Karl, thanks for the question.  

It is said that there are some from 7500 different apple varieties. Just an external visual probably won't give you a positive ID.  You can get a DNA test for a few hundred dollars.  You can also use a tool to help narrow down your choices.  Shape, harvest time, taste, flesh color, along with other features can probably get you down to a few varieties.  The following links, including an ID tool, will help you do your own research.  Check them out:

I hope this helps.

Not helpful.

Not helpful. The first link starts by saying identifying apples is very difficult. The 2nd link is for a youtube video that is more commercial than eductional. The 3rd link is for apple trees is East England, which is not Cheboygan, Michigan, or even on the North American continent. Sending me to links that cannot help me or lead to the answer asked is not helpful. Its a great example of American customer service but not helpful.

Hi Karl,

I am sorry I was not helpful. The true way of determining the variety is DNA (Foundation Plant Services (ucdavis.edu)).  Even then, this may be a wild apple and not a true cultivated apple. The FruitID link does include many varieties found in the U.S. It has a good pictures of the variations in fruit color and other details of the various cultivars needed to make a good ID.   Here is another data base that can be searched but is not as detailed including 217 US and 40 Canadian cultivars: Search the Orange Pippin fruit tree database. If this does not work for you, you can take samples to the Cheboygan County Extension Office - Cheboygan County (msu.edu). Again, I am sorry that I did not meet your expectations.
