Jon Kramer is an adventurer first, and also a geologist, writer, climber and surfer (but not necessarily in that order, depending on the surf). He received his Bachelor of Science degree in geology at the University of Maryland and has pursued life as an adventuring paleontologist ever since. His interests are quite varied and include all things natural. In addition to popular travel and adventure writing, Jon has published scientific papers on critters as ancient as 2 billion-year-old bacteria and as young as 12,000-year-old mammoths. Jon travels extensively with his wife Julie, sometimes settling down for a rest in Minnesota, Florida, California and interesting points in between.
