Ultima thule

"The poems are set above and below the cave country of south central Kentucky, where McCombs lives. The book is framed by two sonnet sequences, the first about a slave guide and explorer at Mammoth Cave in the mid-1800s and the second about McCombs's experiences as a guide and park ranger there in the 1990s. Other poems deal with Mammoth Cave's four thousand year human history and the thrills of crawling into tight, rarely visited passageways to see what lies beyond. Often the poems search for oblique angles into personal experience, and the caves and the landscape they create form a personal geology."--BOOK JACKET.
