Dry gravel would be considered stable on a slope with an angle of repose of 35°. Gravel has a higher angle of repose than sand, and the fact that it is dry means the particles are likely locked together tightly enough to resist sliding. Wet sand or water-saturated sand would be more likely to experience slope failure, and well-rounded sand would not necessarily provide stability on its own.
