It took 16 years, but it was SOOO great to take students back to Hawaii to get a first-hand education in volcanology and active voclanoes.  There are no volcanoes anywhere near Ottawa, so this is a big part of our students training.  Also, many of our students get jobs in the miing industry where many deposits are hosted in volcanic rocks - how can you interpret old, tilted, folded and metamorphosed volcanic suites if you have not seen fresh modern ones?  The trip included time on three islands:  Oahu, Maui and the Big Island.  Oahu has arguably the best exposures of rejuvenated stage volcanoes all within an easy drive of Honolulu.  Maui (especially Haleakala) has terrific examples of post-shield volcanism, and West Maui is well known for the occurrence of trachytes during the post-shield stage.  The Big Island has three active volcanoes and a dormant one tat include superb exposures of shield and post-shield lavas.  So no trip is complete without seeing all three islands!  I had help from Marie-Pierre Nantel (course TA); Rick Hazlett who led us on an excellent geo-biology-ecology walk along the Puu Oo trail at Mauna Loa; Gary Sleik, photographer extraordinaire, who took the group on a hike over the 2010 Puu Oo lava flows from his house at Kalapana to the ocean; and Richard Ernst and Hafida El Bilali who asked to come along on the trip and were incredibly helpful.  The students paid for a good part of the trip themselves, and were financially supported by the Collins and Sethu Raman endowments to the Department of Earth Sciences at Carleton University, and one student was funded by the NSERC iMAGE-CREATE program based at the University of Ottawa.
