solid as rock

But somehow Gharbaoui made them as solid as rock.

They hasten from the east In unending files; Their arrows speed like lightning; Their chargers are shod with swiftness; Their chariots are solid as rock.

The stream was broad, rapid, turbid, but the bottom solid as rock.

It was as solid as rock in place––just as if the whole mountain had slipped!”

It was a lonely, hideous waste, rendered the more shocking by the consideration that the whole vast range was formed of blocks of frozen water which warmth would dissolve; that it was a country as solid as rock and as unsubstantial as a cloud, to be shunned by the mariner as though it was Death's own pavilion, the estate and mansion of the grisly spectre, and creating round about it as supreme a desolation and loneliness of ocean as that which reigned in its own white stillness.
