Nature Alphabet Challenge part 1

 My daughter suggested this challenge. Here are the rules as I understand them:

1. Find the letters (upper or lower case) of the alphabet in nature.

2. You may not alter nature in any way.

Here's what I have found so far:

A

(Nothing said I couldn't turn the camera 90 degrees!)

B

Can you see it?

C

D

E

F

G

(Takes a little imagination!)

H

I I I I I I I I

J

K

L

I think the water falling makes an "L".

M

Follow the tree tops.

More when I find them!
