By The Lyubisha River

On Dennitza, the Kazan is a large astrobleme. During glaciation, a colter of ice pierced the Kazan ringwall, then the melt-begotten Lyubisha River formed a canyon. Flandry watches the broad, brown river which is:

"...quiet except where it chuckled around a boulder or a sandbar near its banks."
-Poul Anderson, A Knight Of Ghosts And Shadows IN Anderson, Sir Dominic Flandry: The Last Knight Of Terra (Riverdale, NY, 2012), pp. 339-606 AT p. 524.

(In Anderson's Time Patrol series, time is compared to a river with changeable features like sandbars that can divert its course.)

"...ocherous palisades..." are "...maned with forest." (ibid.) Leaves are bluish-green or plum-coloured.

"...trees...grew taller than the taiga granted." (ibid.)

My points are, first, that Anderson shows us an alien landscape where, e.g., we must not assume that leaves are Terretrial green and, secondly, that his vocabulary is rich even when describing features that might be common to Earth and Dennitza.
