Both the banner image and the header respond to scrolling the page. The header will shrink to become less obtrusive when you have scrolled a certain distance down the page. And the banner image will fade out and move up in relation to the distance you've scrolled.
Contact Form or Location Dropdown in Header
Adirondack has a built-in contact form or location info and map, opened with the icon in the upper right. You can choose which to display (or to display neither) with the Header Dropdown option in the Style Editor. The location dropdown uses an auto-generated google map image.
