Alpine is a GPL v3 Wordpress theme by the same name that I converted to Drupal 6 originally. Since Drupal 7 has been released, I have also updated Alpine for Drupal 7.
I have already added some extra regions and plan to add more in later versions. There is also a 100% CSS Only Primary Links menu dropdowns for Drupal 6 and Main Menu drop downs for Drupal 7. Alpine features some great default images and styles, but can be easily modified with your own images. It is great for a nature blog, hiking blog, and generally any other outdoors or nature related website.
