Images of Keyline, Keypoint, Berms, & Terraces: share for teaching & education

"Keyline design is a technique for maximizing beneficial use of water resources of a piece of land. The Keyline refers to a specific topographic feature linked to water flow. Beyond that however, Keyline can be seen as a collection of design principles, techniques and systems for development of rural and urban landscapes.
Keyline design was developed in Australia by farmer and engineer P. A. Yeomans, and described and explained in his books The Keyline Plan, The Challenge of Landscape, Water For Every Farm, and The City Forest.
David Holmgren, one of the founders of Permaculture, used Yeoman's keyline principle extensively in the formulation of Permaculture concepts and the design of sustainable human settlements and organic farms.
Darren J. Doherty has extensive experience across the world in keyline project design, development, management & training.
Keyline also includes concepts for rapid soil fertility enhancement and these concepts are explored in Priority One by P. A. Yeomans' son Allan. Yeomans and his sons were also instrumental in the design and production of special plows and cultivating equipment for use in conjunction with the keyline methodology."

Since creating & teaching many permaculture Impress (LibreOffice's answer to Powerpoint) classes I've collected quite the archive of images related to permaculture. I feel it would behoove our online community to share our images for learning & teaching purposes. All images shared with adherence to & respect for attribution: always telling others the source where you got the image.
We can even use the concept of permaculture zones:
Zone 1: share images that you have taken & created of your projects,
Zone 2: share images that you have taken & created of others' projects,
Zone 3: share images from the Creative Commons, Public Domain, & other other copyleft licenses (eg. the WikiMedia Commons),
Zone 4: share images from permaculture websites, this way they can be attributed & it will hopefully draw more attention to their projects,
Zone 5: share relevant images from any other sources. Fair Use Doctrine may apply in the U.S. (and possibly other countries?) for nonprofit educational use.
Without further ado, I'd like to present what images I've collected so far from my "Keyline, Keypoint, Berms, & Terraces earthworks" class. Note, I've not used all of these images in class, I just saved a lot during my research.
Please feel free to upload your Keyline, Keypoint, Berms, & Terraces earthworks images to this thread!
