Suddenly I wanted to see the jetty again, so I hopped in my car and drove to the remote site. I saw the Spiral Jetty was now high and dry. Drifting sand had already started to bury parts of it. The water’s edge was now over 300 yards away. I thought of the millions of migratory birds that would be arriving in the spring to rest and feast on the tiny treasures of the lake, the brine shrimp. I hoped a smaller lake would still be enough for all of them.
The recent words of the director of Friends of the Great Salt Lake, Lynn de Freitas, rang in my head: “The Great Salt Lake is a gift that keeps on giving. Just add water.”

Alongside planting the rain through water harvesting earthworks, we installed an ecological design with a fruit and shade producing overstory, and an understory of shrubs, plants, and grasses. The understory performs one or more of four functions: pollinator attractors, nitrogen fixers, nutrient accumulators (which pull nutrients deeper in soil layers towards the surface, becoming available through a chop and drop technique), and soil stabilizers. Now, broad-tailed hummingbirds, spotted towhees, rock wrens and more can be seen and heard as the garden bounty ripens each year. These birds bring color, song, and delight as they contribute to pest control, devouring aphids, grasshoppers and pesky plant eating beetle grubs.
What we have learned through our small urban campus is that with permaculture design, any landscape can undergo a complete ecological transition – even a landscape that is only a few feet wide and was previously partially covered in concrete.
If you are interested in applying permaculture design to your landscape, start by observing your site as it currently is. See how water flows in a rain event. Walk around during the hottest days of the year and feel where the hot and cool zones are. How does the sun move across the site during summer solstice. During winter solstice. What views do you want to take in and block? What species engage in your landscape and what ones are missing? These are the types of questions you can ask yourself. Then, as you begin to think about design ideas, here are some general tips:
Ask elders in your community about extreme weather events and other helpful historical information
Think about what your landscape is currently doing for you, and what you would like it to do. Then, develop your goals for the site. This will help you determine what is and is not currently working
In the desert, as a general rule, place your paths high and dry, plants low and wet (or at least wetter)
Discover what plants might work well together in what is called a guild. For example, if you have a nitrogen dependent shrub, plant nitrogen-fixing plants around it.
Harvest as much rainwater as possible through active systems like rain tanks, and passive systems like earthworks that slow, spread, and sink rainwater
Plant your high-maintenance plants in your most-frequented areas – alongside the pathway between your house and chicken coop, for example.
Birds and humans appreciate diversity in heights, species, and food-producing plants
Start small
See failures as opportunities for learning

Karst topography’ refers to landscapes cleaved apart by the leaching of water through a soluble bedrock layer comprised of carbonate-rich rocks like the limestone and dolomite found throughout Utah’s mountains or the evaporate-type gypsum and rock salt layers found in Utah’s redrock country. Over time, this erosion by surface and groundwater creates pinnacles, rippling fissures, gaping sinkholes, or springs on the surface—deep caverns, plummeting vertical shafts, and winding tunnels through which entire rivers can flow below.
We floated one such river once, in complete darkness, guided only by a subtle current and the voice of our local guide. He said he was of Mayan descent, so we listened closely when he relayed stories of Chaac, the Mayan god of rain responsible for the generous flow of water through the caverns we explored. Indeed, it is within these same caverns that he dwells, we were told. Further north, in Mexico and the desert southwest, it’s Tlaloc, the goggle-eyed Aztecan deity that controls the rain. He, too, is supposed to reside within the body of the earth.
Main Drain is Utah’s deepest and the nation’s 11th-deepest cave. It’s also wildly difficult and dangerous to navigate, yet absolutely critical to explore for the sake of furthering scientific understanding. I talked to Larry Spangler of the US Geological Survey in Salt Lake City about the significance of karst landscapes like Main Drain. “The caves that are developed in these terrains,” Spangler says, “are…valuable sources of information in regard to changes in climate and landscape evolution over time.” The chemistries of these caves are unique to their environment, and analysis of mineral deposits within the caves can provide insights into how average surface temperatures have changed over time and how wet or dry the landscape above was in any given period. Karst caves can reveal climate data for specific locales that may help us predict how a warming planet might affect our local ecosystems.
The water that flows through Main Drain and other cave systems like it in the form of snowmelt and subterranean streams carves its way vertically and horizontally through layers of bedrock hundreds of millions of years old—providing researchers a literal inside look at the formation of mountains. And as a map of these subterranean watersheds begins to come together, we gain a better understanding of the hydrology of an area and its effects on water quality.
When I spoke to Spangler, he wanted to make it very clear just how sensitive these karst landscapes are to surface activities, for the health of ecosystems and the integrity of watersheds, of course, but also for the health of human communities. The US Geological Survey estimates that as much as a quarter of the world’s population depends on karst landscapes for their water supply. The city of Logan, where my family and I live, sources its water from one of the larger karst springs in the area. The people are drinking straight from the mountain.
Rivers run beneath these hills, and through us as well.
Author’s note: Caves and other karst features are inherently dangerous. You should never enter a cave or other karst feature without the appropriate training, gear, and an experienced person(s) to accompany you.
