LASAGNA GARDENING: THE "CORN HILL"

Raw Materials:

Cardboard
Dirt: Desert sand. The entire Salt Lake area lies in the former lakebed of historic Lake Bonneville, and it all turned into desert after Lake Bonneville mostly dried up (the Great Salt Lake is all that's left of it).
Mulch: Mulched grass clippings, including cottonwood leaves that got mulched by the lawnmower.
"New Garbage": Household garbage which, after being stored in garbage cans for several weeks ... decays/ferments/molds, and eventually turns into ...
"Old Garbage": A few orange peels and peanut shells can be detected, but mostly it's smelly black goo.
Steer Manure: A commercial product. Doesn't smell nearly as bad as the Old Garbage.
Water.

Assembling the "Corn Hill":

We start with an empty hole about six inches deep. In this case, it's about 48 inches square.
Add a layer of cardboard, water it, and (ideally) let is soak for a few days.
Add a layer of dirt and water it.
A layer of mulch, and water it.
Another layer of dirt, and water.
A layer of Old Garbage, and water.
Another layer of dirt, and water.
Add a layer of the steer manure, and water.
More dirt, and a final watering. Ready for planting!
