Do not be alarmed! This is not an invasion of giant mutant frogs! This granite boulder in the hills of central Arizona was painted by Sara Perkins and her two sons in 1928 to emphasize its natural resemblance to a crouching frog. Now, the residents of the nearby town of Congress redo the paint job as necessary to keep the jolly giant green.
Directions: The town of Congress is 16 miles northwest of Wickenburg, Arizona via paved Highways 93 and 89. From the intersection of Highways 89 and 71 in "downtown" Congress, continue about 1 mile northeast on Highway 89. The frog rock is on the northwest side of Highway 89. The rock is behind a barbed wire fence, but is easily visible from the highway.
