Maple tree disease
I live in Michigan. This winter we noticed orange spots all over the snow underneath our Maple tree (a large area of the snow was orange). This spring we noticed that several branches of the tree were black. Now very few of the branches have leaves. Most are toward the center of the tree and the leaves don't look healthy. Any idea what it is? Is the tree salvageable? If not, can we plant another maple in its place?

It is certainly a fungus, but which one and how salvageable the tree is will be difficult to determine online.
With tree diseases, it can be very difficult to assess the health of the tree without seeing the tree in person. I would recommend that you contact your local extension service and ask if they can either have someone come and examine the tree or recommend a good aborist in the area to look at the tree. You can find your closest extension office (there is certainly one in your county) with this tool: https://www.gardeningknowhow.com/extension-search/
