Sutherland Falls is a waterfall near Milford Sound in New Zealand's South Island. At 580 metres (1,904 feet) the falls were long believed to be the tallest waterfall in New Zealand. However, Browne Falls cascades 843 metres (2,766 feet) down a mountainside in Doubtful Sound, leading some to view that as the tallest. The beautiful water falls in three cascades, the upper is 229 m tall, middle - 248 m, lower - 103 m tall. Vertical fall of 580 m is made over 480 m of horizontal distance, thus the mean grade of falls is approximately 56 degrees.
