|The watch tower of Quasqueton as depicted by David Sutherland; scan from Old School FRP|
"Far from the nearest settlement, away from traveled routes, and high upon a craggy hill, the new construction took shape. Carved out of the rock protrusion which crested the heavily forested hill, this mystical hideaway was well hidden, and its rumored existence was never common knowledge. Even less well known was its name, the Caverns of Quasqueton ... Vast amounts of rock were removed and tumbled off the rough cliffs into large piles now overgrown with vegetation. A single tower was constructed above ground for lookout purposes, even though there was little to see other than a hilly, forested wilderness for miles around" (pg 6; bolding added for emphasis)
"The Caverns of Quasqueton ... are hewn from a great rock outcropping at the crest of a large wooded hill. Winds buffet the hill continuously, blowing and whistling through the trees, vines, and other vegetation which blanket the prominence on all sides" (pg 7)
"A cave-like opening, somewhat obscured by vegetation, is noticeable at the end of a treacherous pathway which leads up to the craggy outcropping of black rock. By sweeping aside some of the vines and branches the opening becomes easily accessible to human-size explorers. The opening leads straight into the rock formation, with a 10'
wide corridor leading the way to a large wooden door ... " (pg 8)

Notes: The image above is a great visual aid for players from the back cover of the original monochrome version of B1, which was included in some versions of the Basic Set. When the module was revised in 1981 for the Moldvay Basic set and reissued with a new brown-colored cover, this image was unfortunately not included.
(I'm starting this quote of the week feature to highlight some of my favorite passages from Holmes Basic & the writings of J. Eric Holmes)
Update: This image possibly shows the pathway/entrance to Quasqueton. See this post for an annotated image.
