• Bergstrom Aircraft - Floods Tours by Air- Located at the Pasco Airport; is a sponsor of the IAFI. A flight with Bergstrom’s offers a unique way to see flood features. It truly is the best way to see some kinds of features; and may be the only way to see others. We suggest scheduling your flight very early in the day- within a few hours of dawn- so that the low-angled light accentuates the contours. Evening hours work as well when mega-ripple features just jump out at you under a low-sun. More information at http://www.bergstromaircraft.com/

• Leavenworth to Wellington Field Trip Guide- This field trip will take us on a transect from the eastern edge of the northeastern Cascades in Leavenworth to just west of the Cascade Crest at the old Great Northern railstop of Wellington. Enroute, we will see evidence for a variety of rock types, geologic structures, climates, glaciations, river and stream processes, vegetation, landslides, wildfires, and snow avalanches.  This transect is an area of much historical significance because it has been a main transportation corridor since 1893. It is perhaps because of the intersection of transportation with geology, topography, climate, and vegetation that this area is most famous. While fire and avalanches have impacted this area for centuries, it is only in the last century with the growth of human population and infrastructure in the mountains that that these events have truly become hazards. Our final stop will explore a classic Cascade hazard—snow avalanches--at Wellington, the site of the deadliest snow avalanche disaster in North America. Leader: Karl Lillquist - CWU Geography. 4.5 MB Field Trip Guide
• Lower Grand Coulee Field Trip Guide- The Lower Grand Coulee extends from Dry Falls to Soap Lake. It is perhaps the most striking of the coulees of the Missoula Flood-created Channeled Scablands. We will explore saline lakes, ice age lakes, hanging valleys, flood bars, giant current ripples, folded Columbia River Basalts, butte and basin topography, potholes, caves, rhino casts, and human activity related to the ice age floods in the Lower Grand Coulee. Stops will include the Ephrata Expansion Bar south of Soap, Soap Lake (a closed basin lake at the downstream end of the Lower Grand Coulee), a flood bar covered with giant current ripples at the mouth of East Lenore Coulee, Lake Lenore caves (notable as models of human occupation sites in the area), and Dry Falls at the head of the coulee.

• Moses Coulee to Chelan Field Trip- The Mid-Columbia River between Moses Coulee and Chelan lies at a key natural boundary. Geology, physiography, climate, and vegetation change dramatically from west to east along this boundary. To the wetter west, lies the coniferous forest-shrouded Cascade Range and associated crystalline rocks of the Swakane and Chelan Mountains terranes. To the east, we see more arid, shrub steppe of the Columbia Plateau and underlying Columbia River Basalts. The northern portion of this area was shaped directly by the late Pleistocene Okanogan Lobe of the Cordilleran Icesheet while ice age floods impacted areas to the south. Our trip will focus on evidence for these intermingled glaciers and floods in this distinctive boundary environment. Stops will focus on key features of the flood and glacial story between Moses Coulee and Chelan. Leader: Karl Lillquist - CWU Geography. 4.5 Mb Field Trip Guide

• Western Quincy BasinField Trip- Ice Age floods entered the Quincy Basin from the northeast and east. Some of this water drained from the basin through the Drumheller Channels to the south. The remainder flowed west, exiting the basin through Frenchman Coulee, Potholes Coulee, and Crater Coulee on the western edge of the Quincy Basin. We will examine the landforms and sediment evidence for late Ice Age catastrophic flood origins and evolution of the western flood outlets. Along the way, you will see giant basalt columns, dry falls, potholes, plunge pools, buttes, mesas, flood bars, dunes, and more. Additionally, we will examine evidence of earlier Ice Age floods into the Quincy Basin from the Columbia River Valley - Apr 23, 2017, Nick Zentner
