Pre-heat the oven to 375°F.

Wash, peel, pit, and slice the peaches into a large bowl.

Add in the sugar, salt, corn starch, and cinnamon; and mix it all together really well.

Pour the peach mixture into an 8"x8" pan or a 7" to 9" baking dish and set aside.

Mix together the oats, flour, brown sugar, cinnamon, and nutmeg in a separate mixing bowl.

Using a pastry blender, cut the butter into the oat mixture until you have a very crumbly mixture.

Crumble the topping over the peaches in the baking dish.

Bake at 375°F for about an hour, or until the top is a deep golden brown.

Remove the crisp from the oven and allow it to cool.

Serve while slightly warm or cooled with vanilla ice cream or whipped cream.
