Safety details
American Whitewater rates Marble to Redstone Class III–IV and describes an approximately 11.5-mile reach. This is a committed moving-water run for experienced Class III–IV boaters with rescue capability, not a beginner or casual flatwater float.
- The Crystal River assessment maps this reach to USGS 09081600 and reports 100 cfs minimum navigable, 550 cfs minimum acceptable, 800–2,000 cfs preferred, and 3,000 cfs maximum acceptable. Treat these as conservative planning cues with same-day scouting; tributaries, wood, culverts, and local channel conditions can differ from the gauge.
- The run has continuous rapids, blind curves, undercut rocks, cold water, strainers, and large boulders requiring quick maneuvering. The two highway culverts require mandatory portages and must be scouted before committing; never attempt to run an obstructed culvert.
- High water changes the character sharply: American Whitewater documents a 2014 Bogan Canyon incident at approximately 1,700–2,300 cfs involving a strainer and Class V conditions. Do not infer that the upper end of the planning band is suitable for every crew or craft.
- Use only the named Yule Quarry Bridge/Marble access and Redstone take-out or a separately verified public access. The valley includes private property and restricted shoreline; do not trespass to scout, portage, land, or camp.

Access map
Put-in
Yule Quarry Bridge / Marble-area public accessUse the Yule Quarry Bridge/Marble-area access and Redstone take-out only after confirming current signs, parking, carry-down, and lawful shoreline access. Coordinates are approximate planning anchors, not surveyed ramp points.
Take-out
Redstone Crystal River take-outThe Crystal valley includes private parcels and restricted fishing or shoreline areas. Do not trespass for a better put-in, scout, portage, take-out, or campsite; use only marked public access or a separately verified permission.

Access notes and hazards
Access caveats
- Use the Yule Quarry Bridge/Marble-area access and Redstone take-out only after confirming current signs, parking, carry-down, and lawful shoreline access. Coordinates are approximate planning anchors, not surveyed ramp points.
- The Crystal valley includes private parcels and restricted fishing or shoreline areas. Do not trespass for a better put-in, scout, portage, take-out, or campsite; use only marked public access or a separately verified permission.
- Scout both highway culverts from the road before launch. Treat each as a mandatory portage and carry around any wood, debris, or unsafe current; keep the crew together and preserve an alternate exit above the first culvert when feasible.
- Bogan Flats is a designated campground with river-adjacent sites, but reservations, seasonal operations, fire restrictions, bear rules, and river-entry conditions change. Confirm the current Recreation.gov listing and do not assume a campsite is available or a formal boat ramp exists.
- The route must end at the named Redstone take-out before the separate downstream Crystal reaches. Do not continue through private or unverified access areas.
Watch for
- USGS 09081600 below 100 cfs, above 3,000 cfs, rapidly rising, unavailable, or inconsistent with the reach assessment and local visual check
- Class III–IV current, blind curves, undercuts, boulders, wood/strainers, cold water, mandatory culvert portages, high-water Class V escalation, and limited recovery
- Gunnison County Road 3/Highway 133 access changes, private-property boundaries, campground reservations/fire restrictions, road closures, and failure to exit at Redstone

NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Named public corridorMarble to Redstone / Bogan Canyon; approximately 11.5 miles; Class III–IV
American Whitewater names the reach, length, difficulty, and direct association with Crystal River above Avalanche Creek near Redstone. RiverBrain provides the named Yule Quarry Bridge access, Redstone take-out, and mandatory culvert portage context.
- Direct live gauge and flow gateUSGS 09081600; 100 cfs minimum navigable, 550 cfs minimum acceptable, 800–2,000 cfs preferred, 3,000 cfs maximum acceptable
USGS provides continuous discharge and gage-height telemetry. The Crystal River recreational-use assessment maps Reach 3, Marble to Redstone, directly to 09081600 and publishes these station-tied thresholds.
- Lawful endpoint and access contextYule Quarry Bridge/Marble-area public access to Redstone take-out
American Whitewater and RiverBrain name the access pair, while the Marble Tourism Association documents the Marble-to-Bogan Flats paddling corridor and public-access context. Confirm current signs and county/land-manager conditions on site.
- Safety boundaryAdvanced Class III–IV; cold water, wood/strainers, undercuts, blind curves, and two mandatory culvert portages
RiverBrain documents continuous hazards and mandatory portages; American Whitewater documents the Class III–IV reach and a high-water 2014 incident involving a strainer and Class V conditions. Scout before launch and do not run an obstructed culvert.
- Camping and logisticsBogan Flats Campground, designated White River National Forest camping along the Crystal River
Recreation.gov identifies Bogan Flats as a White River National Forest campground beside the Crystal River with designated tent/RV sites. Reservations, seasonal status, fire restrictions, bear rules, and any river access must be confirmed separately.
- Coordinate evidenceApproximate Yule Quarry Bridge put-in and Redstone take-out mapping anchors
The endpoint coordinates follow the published Marble-to-Redstone mapping reference and are intentionally labeled approximate. Verify the physical public access and river exit before launch.
- Duplicate separationDistinct Crystal River Marble-to-Redstone reach ending before downstream Crystal sections
The station-tied assessment identifies Marble to Redstone as a separate reach from Crystal Gorge, Meatgrinder, The Narrows, Avalanche Creek to BRB Campground, and BRB Campground to the Roaring Fork. This route is also separate from the unrelated Wisconsin Crystal River proxy route.
