Preheat the oven to 400° and line 2 baking sheets with parchment paper. In a large bowl, combine the all-purpose and whole wheat pastry flours with the granulated sugar, baking powder, baking soda and salt. Using a pastry blender or 2 knives, cut in the butter until the mixture resembles coarse meal. Stir in the 1 1/4 cups of buttermilk and carefully fold in the sliced strawberries.
Using an ice cream scoop or a spoon, scoop the dough into 16 mounds on the prepared baking sheets. Brush the scones with buttermilk and sprinkle with the turbinado sugar. Bake in the upper and lower thirds of the oven for 30 to 35 minutes, until the scones are golden and cooked through; shift the pans from front to back and top to bottom halfway through baking. Let the scones cool on a rack for 30 minutes.
Lower the oven temperature to 350°. Spread the almonds in a pie plate and toast for about 8 minutes, until golden. Meanwhile, in a small bowl, whisk the confectioners' sugar with the buttermilk, almond extract and salt. Cover and let stand at room temperature.
Drizzle the scones with the glaze, then top with the almonds, pressing to help them adhere. Let dry for 10 minutes, then serve.
