Preheat the oven to 350 degrees. Rinse the cherries and peaches in warm water. Remove the pits from two cups of cherries and place the halved cherries in a 9x13 pan. Cut the peaches in half. Remove the pit and cut the peaches (keep the skins on) into bite sized, small pieces. Place the peach pieces into the pan with the cherries. Stir them together. In a bowl, place the stick of butter. Have the butter be at room temperature or microwave for a few seconds until it's slightly soft. To the butter add the brown sugar, oats, flour and dash of salt. Sprinkle the crumble over the peaches and cherries until it's evenly spread on top. Place the cobbler into the oven and bake for 25-30 minutes, or until the crumble is golden brown. When the cobbler is cooked, serve with vanilla ice cream.
