Abstract
A complex and accentuated karstland at 61-62 deg N in the Nahanni area of the Mackenzie Mountains, Northwest Territories, Canada, was explored and studied in 1972-74. The climate is subarctic, continental interior type, and there is a discontinuous permafrost. The findings added knowledge of karst styles and suggested that some relationships between karst morphology and climate be reassessed. A new karst style, labyrinth karst, was recognized in climates ranging from humid tropical to subarctic. These karst landscapes were identified in several humid and seasonally humid tropical carbonate terrains such as southwest Celebes, Indonesia, the Star Mountains and Lake A jamuru regions of New Guinea, and the Tanga region of Tanzania. They also were clearly visible in oblique photographs of the Sierra Maestra in Cuba and Arnhem Land, Northern Territory, Australia. In the late stages of evolution, labyrinth karst was replaced by limestone towers. This indicates that tower karst is polygenetic and not specific to the humid tropics as was once thought.
