reds and browns and grays and vermilions more appealing to the eye
than they are as they softly glow in this great canyon. The
color-scheme runs from the dark, sombre hue of the gneiss at the
bottom, up through the yellowish brown of the Cambrian layers, and
on up through seven or eight broad bands of varying tints of red and
vermilion, to the broad yellowish-gray at the top.

The north side of the canyon has been much more deeply and
elaborately carved than the south side; most of the great
architectural features are on the north side--the huge temples and
fortresses and amphitheatres. The strata dip very gently to the
north and northeast, while the slope of the surface is to the south
and southeast. This has caused the drainage from the great northern
plateaus to flow into the canyon and thus cut and carve the north
side as we behold it.

The visitor standing upon the south side looks across the great
chasm upon the bewildering maze of monumental forms, some of them as
suggestive of human workmanship as anything in nature well can be,
--crumbling turrets and foundations, forms as distinctly square as
any work of man's hands, vast fortress-like structures with salients
and entering angles and wing walls resisting the siege of time, huge
pyramidal piles rising story on story, three thousand feet or more
