Hi Mr. Wood. I'm Joey Pham from period 2. I got the answers to the problem. I think it is when the snow forms a bubble and then it pop so it forms a big hole like a bubble gum getting pop in your mouth. Also i think there is 4 oxbow lakes. Have fun in the snow. Also, i got your elective and you are not here, so i am so sad. Be back as soon as possible. Bye
