Clementi (née Eyres), Marie Penelope Rose (tháng 12 năm 1916), “A Journey to the Summit of Mount Roraima”, The Geographical Journal, London, Anh, U.K.: Blackwell Publishing, on behalf of the Royal Geographical Society, with the Institute of British Geographers, 48 (6): 456–473, doi:10.2307/1779816, ISSN0016-7398, JSTOR1779816, OCLC1570660, The summit is covered with enormous black boulders, weathered into the weirdest and most fantastic shapes. We were in the middle of an amphitheatre, encircled by what one might almost call waves of stone. It would be unsafe to explore this rugged plateau without white paint to mark one's way, for one would be very soon lost in the labyrinth of extraordinary rocks. There is no vegetation on Roraima save a few dampsodden bushes (Bonnetia Roraimœ), and fire sufficient for cooking can be raised only by an Indian squatting beside it and blowing all the time.
Tate, G. H. H. (tháng 1 năm 1930), “Notes on the Mount Roraima Region”, Geographical Review, New York, New York, Hoa KỳA.: American Geographical Society, 20 (1): 53–68, doi:10.2307/209126, ISSN0016-7428, JSTOR209126, OCLC1570664, In general the interior plateau looks flat and monotonous. Appearance is deceptive, for there are actually very few places where walking is not difficult, and these follow the joint system of the sandstone. For the most part, tumbled masses of rock, rifts, and gorges and whole acres of ten-foot mushrooms and loaves of bread formed in stone offer a maze in which one may wander long before finding better ground; while gullies many yards in depth and breadth, meandering undecidedly, force detours of sometimes half a mile.
