Gravel & Rock ordered online by the ton. A dump truck delivers to your Salmon address and unloads right where you point.







The price you pay for gravel and rock in Salmon depends on two things: the material itself and how much base work your site needs. Ground around Salmon is in dual hydrologic group C/D, so the soil takes water in slowly. That means water runs across the surface, and you need a deeper base layer to keep your gravel from washing out.
Gravel Monkey delivers by the ton straight to your address, so the delivered number is just the material you order plus freight to your ZIP. No minimums or hidden fees. You pick the size and the day, and we handle the truck and the drop.
Pea gravel moves underfoot. River rock does not compact. Crusher run is grey and dusty. Each product has a place, but only if you match it to the right job.
| Material | Best for | Note |
|---|---|---|
| 3/8" Natural Pea Gravel | Play areas, patios | Rounded and smooth; not for paths that need firm compaction. |
| River Rock | Beds, borders, dry creek beds | Smooth stones; does not compact, so not for driveways. |
| 2-4" River Rock | Larger decorative cover, erosion control | Good for slopes; too large for walkways. |
| Drain Rock | French drains, dry wells | Clean angular stone sized for water flow. |
| Decomposed Granite | Paths and patios that compact firm | Not for surfaces that stay wet; needs a base. |
| Crusher Run | Compacting base under everything | Contains fines; can wash out without proper drainage. |
| Road Base | Lanes and pads that carry trucks | Heavy load bearing; not for decorative beds. |

| French drain | Drain Rock | Fill trench 6 to 12 inches; wrap in fabric. |
Lemhi County permitted about 45 single-family homes in 2024, so new construction is adding demand for gravel for driveways, paths and landscape beds. That means you may want to order earlier in the season to secure your spot.
Hard freezes shape the calendar here, so base work is easier to get right from late spring through fall. The deep frost adds another reason to get the base thickness right before winter sets in.
Figuring out how many tons of gravel or rock you need depends on the area, depth and material density. Use our material calculators to get a close estimate before you order.

Yes. Ground freezing here is deep and long, so the base layer needs to be deep enough to prevent heave. You should order base stone well before the first freeze and complete the base work while the ground is workable.
The number of wet days is not tracked locally, but soils in Salmon are commonly poorly drained, so you should plan deliveries for dry spells whenever possible. Wet ground can complicate access and compaction.
The size depends on the project. Pea gravel works for patios, river rock for dry creek beds, and crusher run for bases. Match the size to the intended use and consider local drainage conditions.
