GIVE 125 Campaign - Give 125 "Somethings" — whatever makes the most sense for you — dollars, time, possessions, or yourself. Our goal is for all GSA members to contribute in increments of 125 to show support for GSA during this anniversary year.

GSA kicked off its 125th Anniversary celebration with this extraordinary 22-day adventure to one of Earth's most dynamic ecosystems. Field and lecture programs were designed for both the professional scientist and anyone with an interest in the planet, its life and future. Read the blog and learn more about the journey.

27 May–1 June:
The Great British Tertiary Volcanoes: Exploring the Palaeogene centres of Skye and Rum;
Geological Society of London field trip: Isle of Skye and Isle of Rum, Scotland.
The igneous centres of the NW Highland and Islands of Scotland, have provided the starting point for much of our understanding of petrology. Classic studies like that of Harker (Skye) and Emeleus (Rum), have unravelled the inner workings of volcanic plumbing systems and their products. This trip, based on the Isle of Skye, explores two of these great igneous centres, by foot and boat and will look at layered igneous rocks, sills/dykes, lava flows and explosive volcanism, amongst the backdrop and beauty of the inner Isles of Skye and Rum. Everything from textures to the wide expanse of flood basalts and beyond will be covered, with something for everyone’s volcanic tastes.

The classic view onto the Glencoul Thrust, first described by Charles Callaway in 1883, one of the major structures of the Moine Thrust Belt.
2–7 June: Structure and tectonics of the NW Highlands of Scotland: from deep crust to hydrocarbon reservoirs
Geological Society of London field trip: NW Highlands, Scotland
The NW Highlands of Scotland is classic ground for structural geology. It was here that many of the key concepts were developed, from the recognition and analysis of thrust systems to the discovery of mylonites. The region remains an important test-bed for modern ideas in structure and tectonics, a training ground for the next generation of earth scientists and a home to analogues for faults in offshore oilfields. This five day field excursion aims to provide an overview not only of the geology and tectonics of NW Scotland but also a broad range of faults and shear zones. These chart deformation styles in the deep crust through various forms of mylonites and cataclasites right up to faulting and damage in analogue hydrocarbon reservoirs.

Formations - Inspired by Colorado's geology, composer Jeffrey Nytch has created a 4-movement symphony performed by the Boulder Philharmonic Orchestra on opening (8 Sept.) night of their 2013-2014 season at CU's Macky Auditorium in Boulder. The Phil will do a special performance of Formations at the 125th Anniversary Gala event at the 2013 GSA Annual Meeting in Denver.
