Materials for Alton Projects

Decorative rock does a lot of work on Alton properties. Beds, borders and dry creek beds all take stone that looks good and holds up through a northwest Iowa winter.

River rock is rounded gravel washed out of the Missouri and Mississippi valleys. Use it in decorative beds, along borders and in dry creek beds where you want a soft, natural look.

Large river rock suits dry creek beds, splash pads and heavier decorative work. The bigger stone stays put on bank edges and around downspouts.

3/8 inch Natural Pea Gravel is the smaller rounded option. It works on walkways, in play areas and as patio bedding.

Iowa says Natural Pea Gravel, not pea stone.

For ground cover under beds and around trees, shredded hardwood mulch holds moisture through a dry August. It breaks down over time and feeds the soil as it goes.

If you are building the bed itself, start with black dirt. Screened topsoil gives roots something to work with before the decorative stone goes on top.

Ground and Conditions in Alton

This corner of Iowa sits under a loess mantle over older glacial deposits, so the soil drains but the slopes are long and even. Water moves, and it moves fast when a hard storm hits.

Across the Northwest Iowa Plains, heavy rain arrives as short, hard events. Silt loess on long slopes rills and gullies quickly, which is why an under-built base shows its weaknesses early.

A drive or pad that skips the compacted base course will pump and rut the first wet spring. Class A roadstone is crushed limestone with the fines left in, so it binds and compacts into a surface that carries weight.

Winters here are cold and open, with wind driving frost deep. That means gravel surfaces heave during the spring thaw, and a base that was not built right will show it.

Plan your work for the long season once frost is out. Drying winds and low rainfall mean new base and new seeding both need water held on them.
