Riverside

A short walk south-west of your house’s yard, just west of the Quarry, the river bank called Riverside is your source of Clay and Sand. There’s one clay pit and two sand pits, all dug with a shovel, and each refills the instant you empty it. Since no trader sells Sand, every bit of Glass and Tin you ever make begins here.

What you can gather

Resource	Yield	Tool and mastery	Respawn
Clay pit	4 Clay per dig	Shovel, Building 2	Instant
Sand pits (two)	4 Sand per dig	Shovel, Building 3	Instant
Rocks (two)	1 and 2 Stone, 2 red tech points	Pickaxe, Building 1 and 2	Never
Rhododendron bush	2–4 Rhododendrons, occasionally a Firefly	Hands, Farming 1	Roughly 20 minutes

Nearby, just beyond the bank, you’ll also find three barberry bushes (Berries), two clumps of Brown mushrooms, and a little further south a wild beehive for Honey.

Uses

Material	Becomes
Clay	3 Clay Plates from 2 at the Potter’s Wheel (the twins need six for Two Peas in a Pod); 6 Bricks from 4 in the Kiln, which costs 5 Clay to build
Sand	3 Glass from 3 in the furnace after the Glass technology; 2–3 Tin, bronze’s other ingredient, from 3 in the Sluice Box; 2 per batch of Polished Stone

Zombie diggers

Riverside’s build desk has a Clay Digger Stand, a Sand Digger Stand and a Porter Station, each costing 2 Wooden Planks and 4 Iron Nails. Put a shovel-carrying zombie at a stand and it digs 1 Clay or 1 Sand per shift, depositing it directly into a chest at Riverside, so you’ll want one built there. The porter hauls both to the Factory.

These three unlock with Zombie Digging (50 red, 10 blue), which is among the technologies hidden until both the Quarry cave and the mine passage beneath your house have been opened.
