Three Caucasian hikers in summer clothes walk a dirt path through a wooded meadow during the day.
A group of explorers making their way through unexplored territory in the middle of summer while one drinks water.
The wooded meadow might not be unexplored territory.  Just because the hikers are wearing summer clothes doesn't mean it's the middle of summer.
