Interesting concept... We like it but the green does not seem to go with our color tones/theme. The nps.gov is not using a shield, but an arrowhead. So we don't really want a shield.
#75 is much better but we are hoping for a logo separate from the name. Like the joshua trees! I think you are more on to something being much more related to us parks!
We think that your Joshua Trees (or what look like them) are really very nice. Is there any way you can try a logo like this but not framed inside anything? A Joshua Tree beside US-Parks.com? Maybe even continue with the color tones you are using? Or whatever colors you think are best to fit on top of a photograph. Will leave that up to you. This is referring to #75.
Hi, I choose Joshua Tree to be unique icon for your park. Unfortunately we dont have here. It's nice tree. To have unique icon is important for me for public to remain who you are.
This is how it looks like on dark background. I use this tones to looks more wild, nature, and elegant. It used only two flat colors for effeciency but if you glance the land (under the tree) seems in 3D shape. Hope you like it.
