San Juan River Packing List (Heat, Silt, Petroglyphs, Family-Capable)
Day three at River House Ruin. We'd hiked up the short trail with the crew — six adults, three kids — and were standing in the quiet courtyard of a 900-year-old Puebloan structure when the seven-year-old reached out to touch the wall. His mother caught his hand mid-air. The wall is sandstone, and oils from a single hand transfer enough to start a process that takes another century to undo. We talked it through with him at the rim. He understood. The visit went on.
Most cultural-site failures are not malicious. They're inattention — adults distracted, kids curious, no one having pre-briefed the protocol before the boat hit the eddy. The lesson wasn't "talk to your kids about ruins." It was that on the San Juan, the cultural protocol needs to be embedded in the trip the same way the rapid-running protocol is. Briefed before the put-in. Repeated at every site. Owned by the trip leader.
This article is the packing list for that. It also covers heat, silt, sun, and the family-capable systems that make this corridor what it is.
What the San Juan actually is
The lower San Juan from Sand Island to Clay Hills is 84 miles, 5–7 days, Class II flatwater with one Class III. Warm water, broad meanders, deep silt, and one of the highest concentrations of Ancestral Puebloan rock art and ruins of any river in the West.
The standard 6-day trip:
- Day 1–2: Sand Island to Mexican Hat. River House, Butler Wash panels. Easy water.
- Day 3–4: Mexican Hat to Slickhorn. Goosenecks, the Honaker overlook.
- Day 5–6: Slickhorn to Clay Hills. Ledge drops, Government Rapid, the Lake Powell sediment fan.
This is not a punchy trip. It is a heat trip, a silt trip, and a cultural trip. Family-capable does not mean low-effort. It means low-Class.
The constraint stack — San Juan version
Trip-killers:
1. Heat. Kills people. July at Mexican Hat clears 105°F. The corridor is exposed. Camps have less shade than the canyon-walled rivers. 1.5 gallons per person per day in summer, plus electrolytes. The forecast doesn't care that your shade tarp is in someone else's truck.
2. Silt. Direct-pump water filters clog in five minutes on the San Juan. A pre-settle bucket, an alum drop, or a gravity filter with pre-filter is required. Skin abrasion from silt is a real day-three problem on hot trips — silt + sweat + sun = a forearm rash that lasts a week.
3. Comms. The lower stretch is roughly 30 miles from any paved road. A medical event without satellite communication is a multi-hour problem. One device per group, charged, on.
4. Cultural protocol failure. Touching a panel, walking on a midden, removing a sherd — the consequences play out over decades, not days. Brief the protocol before launch, reinforce at every site.
Trip-degraders:
5. Sun exposure. Less canyon, less shade, more mid-day open water. Sun layers + tarp shade are the system, not a luxury.
6. Boredom on the meander. Goosenecks day is slow water. Without a snack plan, a swimming spot, and one cultural-site stop, the day wears on kids fast.
The mistake the silt discipline is built on
Day two on a different trip. We were running a direct-feed pump filter from the river — pumping straight into a Nalgene because we'd been lazy at lunch. By dish-time the filter was clogged solid. We had a backup gravity filter but no pre-filter on it, and the second filter clogged within an hour. The third option — boil-and-cool — added forty minutes to dinner and ate fuel we hadn't planned for.
The trip didn't fail. But the next two days were on the boil-and-cool plan, fuel was tight by the end, and the kitchen ran slow because every water request was a 30-minute commitment.
The lesson wasn't "carry more filters." We had three. The lesson was: the San Juan is silt before it's water. Your filter, your closures, your skin — all of them know. Pre-settle in a bucket for at least 30 minutes before any filter touches it. The water that looks clean today will clog your pump tomorrow.
Personal kit
Per person, no exceptions.
- 65L–110L personal dry bag. The San Juan's silt is unforgiving on closures — see Best Dry Bags for Desert Rivers for the per-bag picks. NRS Bill's Bag is the workhorse.
- 20L day bag — sunscreen, hat, water, snacks, sun layers.
- PFD — NRS Chinook OS for crew. Type V for any rower running Government.
- Sun layers: long-sleeve sun shirt, sun pants, wide-brim hat with neck flap, polarized glasses on a leash. The San Juan rewards full-coverage sun gear more than any other corridor.
- Drainable closed-toe water shoes that handle silt without grinding into the foot. Closed-toe matters — ledge drops have rebar from old infrastructure in places.
- Sleep system rated for the season — 50°F summer, 30°F shoulder. Spring nights in the goosenecks can drop into the 40s.
- Headlamp + spare batteries.
- Personal medications.
- Electrolyte mix — at least one liter per day per person in summer.
Group gear
If it's not assigned, it doesn't exist. And the person who "forgot" the pre-filter will tell you about it after dinner.
- Kitchen: stove (Partner Steel 2-burner is standard), fuel, table, dish system, cookware. See Best River Camp Kitchen Setup.
- Cooler: 6 days × people × 5 lbs ice/day in summer. Canyon Coolers Outfitter 75 for 4–8 person crews.
- Water system: pre-settle bucket (5-gallon minimum), gravity filter, alum or chlorine for backup, jugs labeled by use. Drinking water and dish water do not share jugs.
- Shade: 10×12 tarp + sand stakes per 4 people. Mandatory above 90°F. The San Juan has less canyon shade than Cataract or Deso — plan for full afternoon coverage.
- Groover: BLM-Monticello spec.
- Repair kit: day-access split from deep-repair. If you can't access it in 10 seconds, you don't have it. See Best River Repair Kit.
- First aid: trip leader carries the group kit. Heat-illness protocol pre-briefed. See Best First Aid Kit for Desert River Trips.
- Satellite communicator: one per group, charged, on. See Best Satellite Communicator for River Trips.
- Cultural protocol kit: a printed BLM cultural-site briefing, optionally a guidebook with site information, no probes/trowels/anything that suggests amateur archaeology.
Per boat
- Frame, oars + spare oar, oar locks + spare pins, throw bag at the rowing position.
- Pump with verified pressure at launch — not "I pumped it last weekend."
- Bow line, stern line, both rigged for camp tie-up and on-water re-rigging.
- Inspect every strap. The strap that fails is always the one you trusted.
Family adjustments
The San Juan is designed for families in a way no other major desert corridor is. The Class is low, the sites are kid-engaging, the camps are walkable.
- Kid PFDs: sized correctly. Always.
- Snacks: load-bearing. Underestimate the snack budget and the eight-year-old does the diplomacy for you.
- Hydration: kids drink less than adults perceive. Track by name. The San Juan in summer is harder on kids than adults — smaller bodies, less heat tolerance.
- Cultural site protocol: brief before launch. Repeat at every site. No touching, no tracing, no moving anything. If you can read it from the river, leave it on the river. Make it a kid-engagement moment, not a scolding.
- Camp routine: swimming spots are a daily anchor. The river is warm and silt-friendly; pick one swim hole per day in advance.
Cultural sites — the protocol
Every group running the San Juan owes the next group through the rules. The ruins and panels are tens of thousands of years of human presence. Touch oils from a single hand can damage rock art for a century. Footsteps on a midden compress a soil profile that took a millennium to form.
- Don't touch. Sandstone walls, panels, mortar. Hands stay back.
- Don't trace. No chalk, no rubbings, no water for "contrast."
- Don't move. Sherds, lithics, masonry — leave it where it lies.
- Don't camp on sites. Even if it looks like a flat sandy spot. If it has a midden, walk on.
- Brief the kids. Every site, every time. Make the protocol theirs.
This is not optional. It's part of the permit, part of the corridor, part of what makes the trip what it is.
What stays home
- "Just in case" cold-weather layers in summer.
- A second pair of sandals. Every raft has a hardback novel nobody read. Don't be the person who packed it.
- Glass containers.
- Anything that needs daily charging but won't get daily use.
- Trowels, probes, brushes, anything that suggests you're going to investigate a site closely. The protocol is hands-off, eyes-on.
One exception: spare valves. Always.
Take-out
Clay Hills is a sediment fan, not a ramp. The take-out shifts seasonally with reservoir levels. Confirm with BLM-Monticello within 7 days of launch:
- Current take-out point and mud-flat distance
- Road condition on the access road from Highway 276
- Any seasonal closures
If you're running the family half-trip to Mexican Hat, the take-out is a paved ramp — significantly easier logistics.
