Description: Thousands of wildebeest prepare to cross the Talek river just as the first few climb out safely

Story from behind the lens: Having hardly had to wait at all before the crossing started I was staggered at how quickly it was all over. As it was one of the smaller herds they were all through in under 10 minutes before a dozen zebra came through at the end.
