Columbus Crater HLS2 Hangout: Exploration Zone Briefing
Columbus Crater HLS2 Hangout: Exploration Zone Briefing Kennda Lynch1,2, Angela Dapremont2, Lauren Kimbrough2, Alex Sessa2, and James Wray2 1Lunar and Planetary Institute/Universities Space Research Association 2Georgia Institute of Technology Columbus Crater: An Overview • Groundwater-fed paleolake located in northwest region of Terra Sirenum • ~110 km in diameter • Diversity of Noachian & Hesperian aged deposits and outcrops • High diversity of aqueous mineral deposits • Estimated 1.5 km depth of sedimentary and/or volcanic infill • High Habitability and Biosignature Preservation Potential LZ & Field Station Latitude: 194.0194 E Longitude: 29.2058 S Altitude: +910 m SROI #1 RROI #1 LZ/HZ SROI #4 SROI #2 SROI #5 22 KM HiRISE Digital Terrain Model (DTM) • HiRISE DTMs are made from two images of the same area on the ground, taken from different look angles (known as a stereo-pair) • DTM’s are powerful research tools that allow researchers to take terrain measurements and model geological processes • For our traversability analysis of Columbus: • The HiRISE DTM was processed and completed by the University of Arizona HiRISE Operations Center. • DTM data were imported into ArcMap 10.5 software and traverses were acquired and analyzed using the 3D analyst tool. • A slope map was created in ArcMap to assess slope values along traverses as a supplement to topography observations. Slope should be ≤30°to meet human mission requirements. Conclusions Traversability • 9 out of the 17 traverses analyzed met the slope criteria for human missions. • This region of Columbus Crater is traversable and allows access to regions of astrobiological interest. It is also a possible access point to other regions of Terra Sirenum. -

Our Tuesday and Thursday Series of Day Hikes and Rambles, Most Within Two Hours of Lake Oswego
Lake Oswego Parks & Recreation Hikes and Rambles Spring/Summer 2015 Calendar of Hikes/Rambles/Walks Welcome to our Tuesday and Thursday series of day hikes and rambles, most within two hours of Lake Oswego. Information is also available at LO Park & Rec Activities Catalog . To recieve weekly News email send your request to [email protected]. Hikes are for hikers of intermediate ability. Hiking distance is usually between 6 - 10 miles, and usually with an elevation gain/loss between 800 - 2000 ft. Longer hikes, greater elevation gains or unusual trail conditions will be noted in the hike description. Hikes leave at 8:00 a.m., unless otherwise indicated. Rambles are typically shorter, less rugged, and more leisurely paced -- perfect for beginners. Outings are usually 5-7 miles with comfortable elevation gains and good trail conditions. Leaves promptly at 8:30a unless otherwise noted. Meeting Places All hikes and rambles leave from the City of Lake Oswego West End Building (WEB), 4101 Kruse Way, Lake Oswego. Park in the lower parking lot (behind the building) off of Kruse Way. Individual hike or ramble descriptions may include second pickup times and places. (See included places table.) for legend. All mileages indicated are roundtrip.

Alkali volcanics are also locally present, pointing to regional differences in igneous processes. Many ma- terials from ancient Mars bear the mineralogic fingerprints of interaction with water. Clay minerals, found in exposures of Noachian crust across the globe, preserve widespread evidence for early weathering, hydrothermal, and diagenetic aqueous environments. Noachian and Hesperian sediments include paleolake deposits with clays, carbonates, sulfates, and chlorides that are more localized in extent. -

(503) 740-5455 [email protected] Don Hamilton, Public Information Officer, ODOT (503) 704-7452 [email protected] UNITED STATES FOREST SERVICE (USFS) AND MULTNOMAH FALLS CO., INC. ANNOUNCE LIMITED- REOPENING OF MULTNOMAH FALLS AND HISTORIC MULTNOMAH FALLS LODGE (Bridal Veil, OR – 11th, 2020) – The United States Forest Service (USFS) and Multnomah Falls Co., Inc. shares today a limited-reopening of Multnomah Falls and the Historic Lodge. The USDA Forest Service in partnership with Oregon Department of Transportation, and Multnomah Fall Co., Inc. will allow access to Multnomah Falls and Lodge in a phased approach. Phase 1 will allow limited access to provide safe and adequate social distancing. This may lead to longer lines in a “queueing area” while waiting to enter the site. The site is available from 9:00 am through 6:00 pm. Phase 2 will introduce a ticketing system which allows access by reservation on ly through rec.gov. Limited number of tickets will be available on hourly basis and must be obtained at least a day in advance of a planned visit. The permit system will be implemented within the next few weeks. “We are dedicated to providing access to the Columbia River Gorge National Scenic Area and Multnomah Falls,” said Lynn Burditt, Forest Supervisor, “through aligning with all state and CDC safety guidelines, addressing safety concerns, and connecting people with this natural and historic treasure.” To provide for the protection of public health and safety and prevent the spread of COVID-19, face coverings are required throughout the area and people will need to maintain social distancing before entering and while visiting Multnomah Falls Recreation Area and the Historic Lodge. -
