You are a scientist named BOB.
You want to know if Cochran Springs Creek or Yarrow Creek is healthier.
After a couple weeks, you FINALLY gather all your data. But then, a heavy wind blows your data away and the data rips on a sharp rock. The pieces of data get blown off a cliff and out into the world. You were only able to retrieve one piece. It's YOUR job to retrieve the rest of the data!!
