The primary time I noticed a spring was the primary time I fished with my buddy Erick Johnson. He introduced me to his favourite bend on a well-known northern Michigan river, the place he confirmed me a muddy despair lined in pine needles. He swept them apart to disclose a small darkish pool of chilly, clear water, watercress-framed, into which he sank a pair of stubby Coors bottles. Later, after an honest spinnerfall and some good trout eventually mild, we drank these numbingly-cold beers on the financial institution, listening to the fish, nonetheless rising at the hours of darkness.
Later I acquired to know spring creeks in Minnesota’s Driftless area. On my first journey there, I keep in mind seeing a three-inch brook trout in a stream I might step throughout, seemingly hovering within the air-clear water. Subsequent to it, a small plume of sand percolated. Mineral-rich groundwater, filtered by means of the traditional limestone hills throughout me, was effervescent into the stream proper there. The trout finned round and thru it. Fontinalis — of a spring — certainly.
I used to be considering of springs, spring creeks, and their magic one dry, sizzling day this summer time. I stood on the sting of the Medication Lake Volcano’s lava dome in northern California, which, regardless of its look, is a novel and immense landscape-level groundwater system.
Behind me was darkish Ponderosa pine forest, mature and open, sighing within the afternoon citrus-scented thermal. Within the distance glinted the snowy cone of Mount Shasta, rags of cloud streaming from its peak like pennants. Earlier than me, a lunar-looking lava mattress descended progressively southward, dotted right here and there with clumps of manzanita, solitary towering sugar pines, and gnarly California incense cedars. The afternoon solar shimmered and bloomed the rock’s black-gray palette into refined orange and cream colours.
Mendacity unassumingly between its conical neighbors, Mount Shasta and Mount Lassen, the Medication Lake Volcano is a protect volcano, named after the lake inside its caldera. Its periodic eruptions over the eons have created practically 850 sq. miles of gently-sloped lava beds, layered on high of each other, making it the Cascade Vary’s largest volcano by quantity. This distinctive construction is collectively known as the Medication Lake Highlands, and is the key behind the area’s important hydrology.
I used to be there as a part of a tour group hosted by Trout Limitless, Backcountry Hunters and Anglers, and California Trout, in help of a marketing campaign to have the Medication Lake Highlands designated as a Nationwide Monument. The marketing campaign was launched in 2023 by the Pit River Tribe, to whom the Highlands — or Sáttítla, as they name it — is ancestral house, and so they’ve been combating in courtroom to guard the realm from geothermal exploitation for many years. TU, BHA, and CalTrout have added their voices to the marketing campaign, recognizing the pure and cultural assets at stake.
Lava cobble crunched underfoot, resonating like damaged glass. I stooped to look at one: lighter than anticipated, its floor porous like a ferrous sea sponge. Sharp edges caught my fingertips. A geologist would name this ʻaʻā lava: the shattered crust of a slow-moving lava movement’s cooling floor. Thus far, moisture had felt conspicuously lacking. No bounding mountain streams, no perched bogs or fens, no muddy elk wallows. None of that speeding gray-blue meltwater that so many different mountains shed by means of the hotter months.
I joined the group on the rim of a swimming-pool sized pit, an ovoid gap punched within the lava’s floor. Angular rubble, the remnants of what had been the roof of this lava tube, shaped a ramp of kinds at one finish of the pit. On the different yawned a black cave opening.
As we fastidiously clambered down into the cave, the air cooled dramatically in a perceptible gradient. It smelled like the within of a clear walk-in freezer. Moist patches of inexperienced moss glittered on the cave partitions. One other pile of rubble blocked the tunnel after about twenty yards, and on the very backside, anchoring the stones just like the toffee a part of peanut brittle, was a thick layer of opaque white ice.
How surreal, we remarked to one another, to really feel that chilly damp, and to see strong ice just some steps from the dry warmth of northern California. However ice caves like this are usually not unusual in protect volcanoes: easy cold-air sinks, insulated and protected against air currents by the lava tube, the place chilly winter air lies undisturbed by means of the summer time months. That ice was the clue: a second of passing water, frozen in time. A snapshot of an in any other case hidden course of.

The Medication Lake lava dome is a colossal sieve. Rain and snowmelt doesn’t run off it in rivers or creeks, however as an alternative filters downward into the rock and slowly migrates down-slope, typically south and west, towards the Fall River Valley. A billion underground trickles, following mysterious and invisible fissures, seams, and layers — at any given time there’s an estimated 20 to 40 million acre-feet of water saved right here. That’s extra water than California’s 200 largest man-made reservoirs mixed.
This reserved water is meted out steadily alongside a 10-mile lengthy groundwater discharge complicated often known as the Fall River Springs. These springs are the first supply of the Fall River, which is California’s largest spring creek, and boasts a few of the highest trout density within the state.
The following morning, we fished it. The river’s banks are largely privately owned, so it’s fished with guides from small motor skiffs, a truth with which I used to be reckoning a bit — on one hand, the possibility to fish unique, ecologically-rich water is thrilling; on the opposite, a few of the magic of discovery is misplaced when you may’t discover in your personal wading boots.
However our guides, with Confluence Outfitters, had been professionals who knew the river, and the magic quickly returned as we motored upstream. In traditional spring-creek trend, there have been no rapids or swimming pools, however as an alternative a delicate meander between grassy banks. Shasta and Lassen gleamed within the hazy distance, however I barely seemed up. As an alternative, I gawked over the bow on the emerald-green spring water, undulating mats of weeds, a heavy sprinkling of rising PMDs, and hundreds of trout. They scooted off sand flats and out of weed pockets by the handfuls. Not occasionally, a two-plus-footer would sulk out of the best way as we drifted over. On some outdoors bends, 40 or 50 snouts dimpled the water as if a reasonably heavy rain had been falling.

Our guides had us swinging moist flies into these pods from upstream. We caught just a few and misplaced lots. I had one heavy fish seize my fly and thrash on the floor simply lengthy sufficient for me to understand it will have dwarfed any Nice Lakes steelhead I’d ever caught — after which the 6X tippet let go.
Amid the cruel montane and volcanic panorama, the Fall River Valley is an oasis. The pastoral fields, the thick grassy banks, the fish and bugs — it appears to be virtually furiously alive. The water itself, impossibly-blue-green, didn’t appear to movement downstream, it surged. There aren’t any cataracts or waterfalls, no dramatic bouldery runs; only a regular inexorable push of clear, volcanic spring water.
As a lot as 1.4 million acre-feet of water pour from the Fall River Springs complicated yearly, and isotope research of the varied sources have proven the water’s age in some to be solely 12 years outdated, whereas others are discharging water that fell as snow over 40 years in the past. This gradual and different motion of groundwater makes the Fall River Springs dependable, even in prolonged intervals of drought.
The Fall River’s movement is added to that of the Pit River, and its year-to-year reliability generates as a lot as 13% of California’s hydropower. The Pit then empties into the Shasta Reservoir, which then turns into the Sacramento River — one other traditional trout water — a lifeline that stretches from the volcanic highlands all the best way to San Francisco Bay. The water helps numerous ecosystems, supplies habitat for native trout and salmon, sustains agriculture within the fertile Sacramento Valley, and contributes to the ingesting water provide for hundreds of thousands of Californians.

The Highlands themselves are a spectacular panorama, worthy of safety on their very own advantage. Medication Lake itself, which sits inside the volcano’s caldera, has been a religious middle for native tribes since prehistory. There are additionally pumice fields by which Apollo astronauts educated for moon landings; a large obsidian formation often known as Glass Mountain; and numerous ice caves and lava tubes. The distinctive forest-over-lava ecosystem helps an extended listing of threatened and endangered species, to incorporate the grey wolf and noticed owl. Undeveloped wild locations like this, particularly these at greater elevations, are more and more uncommon and demanding in a warming West.
It’s inside this context that Monument designation for the Medication Lake Highlands is smart. Geothermal energy exploration is the first industrial menace, largely due to the hydraulic fracturing concerned. The valuable groundwater in that porous rock can be prone to contamination by not solely poisonous fracking fluids but additionally naturally-occurring poisonous volcanic compounds that the fracking would possible launch. For now, the Pit River Tribe’s tireless efforts to dam geothermal exploration has all the present main initiatives stalled.

And there aren’t any different entrenched extractive industries to confront, no communities fearing financial loss. This can be a distinctive likelihood to guard a significant useful resource and invaluable panorama with out controversy — earlier than disaster forces a combat. With altering political winds, vitality wants, and expertise, the Highlands are beneath menace so long as the land stays open to mineral and vitality exploration.
The Highlands exist inside components of the Klamath, Shasta-Trinity, and Modoc Nationwide Forests, and its assets are managed by each the Forest Service and Bureau of Land Administration. Monument designation wouldn’t change any land possession — it will all stay federal public land — however it will assist stop new mineral or geothermal leases, and get rid of the opportunity of land transfers out of federal possession. A administration plan gained’t be created till after designation, however beneath the purview of the Forest Service and the BLM, public entry to and use of the land, to incorporate searching and fishing, would virtually actually stay unchanged.
Ahjumawi Lava Springs State Park was the final cease on our tour. After boating throughout Huge Lake — the one entry to the park — we hiked alongside the shore with members of the Ahjumawi Band of the Pit River Tribe, who lived within the space for hundreds of years. They confirmed us how they’d used rock fish traps to catch the native rainbow trout and Sacramento suckers that they’d depended upon without end.

And so they confirmed us the springs. On the head of an unassuming channel, overgrown with rabbit brush and willows, turquoise-tinted crystal-clear water surged from beneath a rock ledge, pouring over time-worn lava rubble. This was no beer-cooling seep, nor limestone-creek trickle. Extra water was pouring from this single spring than the whole thing of a few of my favourite spring creeks again house. In an inches-deep eddy to 1 facet, glinting in overhead daylight, a six-pound rainbow trout hunted amongst the lava boulders.
It had appeared counterintuitive that almost all of our tour time was spent outdoors the boundaries of the proposed monument. Neither the Fall River Valley, Fall River Springs, nor Ahjumawi State Park are inside it. From the wooded shore of the lake, we couldn’t even see the lava of the Highlands. But right here was its water, pouring from the dwelling rock, chilly and drinkably clear, maybe having fallen as snow on high of a volcano earlier than I used to be born, and relied upon by numerous downstream ecosystems and folks.
Now could be the time to guard it, and presidential designation as a Nationwide Monument is the best option to do it.
