Two stones, weighing 1344 g and 1243 g, fell in the city of Monahans, Texas, after two sonic booms and a fireball were observed over a wide area (up to 100 km from the fall site).  One stone penetrated the asphalt on a city street and was found in the sandy subsurface.  Classification and mineralogy (M.
