I travel to locations where there are caves, volcanoes, lava flows, geysers, icebergs, glaciers, and, most recently, the aurora borealis. These are all iconic natural manifestations that I investigate in light of the nineteenth century idea of the "sublime," a concept that embodies a contradictory relationship between feelings of awe and terror in the face of nature's overwhelming power. That attitude of inherent respect is challenged today by purely utilitarian approaches to the natural world. Ultimately, these paintings and drawings are mental spaces in which emotions evoked by powerful landscapes can be reconsidered.
