Tom Clark's collection of short fiction, The Last Gas Station, is in two contrasting parts. It opens with 23 very short prose pieces--amusingly surreal California vignettes, some no longer than a page, peopled by denim-clad cowgirls, itinerant lover boys, Martin Heidegger, Boris Pasternak, Muslim college students, Vietnam vets, Ty Cobb, Ted Berrigan, and a great dinosaur poet of the Jurassic period. These are followed by the novella "Incident at Basecamp," an odd matter-of-fact account of a close encounter between a young married couple and a spindly, three-toed, mind-reading extraterrestrial somewhere deep in the Rocky Mountain wilderness.
