SUMMARY:Lake Wenatchee Area Field Trip - Cancelled (Again)
DESCRIPTION:Given the ongoing Lower Sugarloaf Fire situation and resulting poor air quality over the region\, I am going to cancel the Lower Lake Wenatchee Area Field Trip planned for Sunday 5 October.  The indefinite closure of US 97 over Blewett Pass has also entered into my decision as it affects those who would be travelling to the area from the south.  I will try to offer this field trip sometime in Spring/Early Summer 2026.  I apologize for any inconvenience this has caused you. \nRetired CWU Geographer Karl Lillquist will lead a field trip to the lower Chiwawa River Valley near Plain\, WA.  Plan on gathering in the vicinity of Plain at about 10am.  Quick description:  Topics will center around alpine glaciation from various sources in the Eastern Cascades near the lower Lake Wenatchee Area.  Trip will begin on the beach in the southern portion of Lake Wenatchee State Park (map). \nDetailed schedule and the topics to be covered: \n\n10:00  Stop 1—Lake Wenatchee State Park—Topics: Bedrock geology; weather & climate; Wenatchee River alpine glacier.\n11:00  Depart\n11:30  Stop 2—Northeast of Fish Lake —Topics:  Fish Lake lobe of the Wenatchee River glacier; moraines & erratics; moraine-dammed lakes; Glacier Peak & Mt. St. Helens tephras.\n12:15  Depart\n12:45  Stop 3—Chiwawa River Valley Overlook—Topics: Chiwawa River alpine glacier; Mad River outlet glaciers; declining contemporary glaciers.\n1:45  Depart\n2:00     Stop 4—Meadow Creek Valley Overlook—Topics: Meadow Creek/Napeequa glaciers; Dirtyface Mountain cirques; Napeequa River capture by White River; moraine-dammed lakes.\n2:45     Depart\n3:15     Stop 5—Deep Creek at Morrow Meadow—Topics: Glacial meltwater\, faulting\, lateral valleys\, and ice age lakes.\n4:00     Depart for home\n\nLogistics: \n\nThis trip is free and open to the public.\nYou will need a Discover Pass for Stop 1.\nAfter Stop 1\, we will drive on a mix of paved and good quality gravel forest roads.  A Subaru-type AWD vehicles should do fine on the gravel roads.\nI strongly encourage you to consider carpooling; parking will be limited at each of the stops and lengthy strings of automobiles can be unwieldy on narrow forest roads.\nWe will take short hikes at Stops 2\, 3 and 4.  By short\, I mean 0.25 mi or less at each stop.  The hiking terrain at Stops 3 and 4 will be fairly steep.  Stops 2 and 4 will involve hiking off trail through recently logged areas.\nNo restroom or picnic facilities are available along our field trip route after Stop 1.  Therefore\, you will need to use the great outdoors if you need to go.  Plan on eating lunch/snacks on the road or at the stops.  There will not be a formal lunch stop.\nDogs and kids are fine to bring as long as they are well-behaved.\nDress for the weather.  September weather here can be sunny and hot to rainy\, windy & cool.\nI will post a pdf of the field guide by 29 August on my CWU website at https://www.cwu.edu/academics/geography/_documents/karl-lillquist.php.  Scroll down the page to “Field Guides”.  You will find it under “Lower Lake Wenatchee Area”.  Feel free to download and bring it on the field trip in digital format or print it out.\nThe Ellensburg Chapter of the Ice Age Floods Institute will also provide ~40 hard copies of the field guide for the trip.  There is no cost for the field guides.  However\, if you are not a member of the Ellensburg Chapter\, please consider making a donation to the chapter to help cover the costs of the field guides (each cost ~$13/each).
