Alpine was originally a Drupal 6 theme that I ported from Wordpress. It is also now available for Drupal 7. It features a 2 Column Layout with a Left Sidebar and Pure CSS Menu Dropdowns. It also has a nice sized header image that can be replaced fairly easily. It is the perfect theme for a hiking blog or nature blog, or any outdoor related website in general.
Please file any issues you have with the theme on our project page.
Thanks and enjoy!
