The oval crater is 50 feet (15 m) in diameter, making it one of the smallest impact craters in the world. Its age is estimated to be less than 1000 years.[3] It has been explored with ground-penetrating radar.[4]
Over 15,000 pounds (7,000 kilograms) of pallasite meteorites have been recovered from the Brenham fall.[5]
