In a large bowl, whisk together coconut, flour, oatmeal, 1/2 cup almonds, granulated sugar, brown sugar, and salt until combined.
Add the diced cold butter. Use your hands to make large crumbles. This will take about 5 minutes to fully work the butter into the oat flour mixture. Just keep squeezing the mixture in your and and eventually the butter-flour mixture will form one large clump.
Crumble the topping over the fruit and cover evenly, then sprinkle remaining ½ cup of almonds over the top. Bake for 50-60 minutes. The the fruit should be bubbling at the edges and the topping and almonds should be golden brown. Here's the hard part: let the crumble sit for at least 15 minutes before serving (it will thicken slightly as it cools). This will stay warm for a couple hours. It reheats beautifully the next day.
