Talk 8 at State Episode 8: Getting Outside with Abby Hepp Transcript
Talk 8 at State Episode 8: Getting Outside with Abby Hepp Transcript Eliza Barsanti: Welcome to the department of Health and Exercise Studies’ Talk 8 at State Podcast with your host, Eliza Barsanti! EB: A couple weeks into the Fall 2020 semester, Covid-19 precautions caused NC State to put all classes online. This switch caused a lot of change in the lives of NC State students, forcing them to step out of their typical day-to-day routines in favor of something different. Abby Hepp ‘23 took this as an opportunity to go on the adventure of a lifetime-hiking, camping, and climbing her way across the United States! Today, we sit down with her to talk about her cross-country road trip, along with advice and NC State resources that students can use to get outside and craft their own adventures. EB: Okay, so today we are sitting down with Abby Hepp. Abby, would you like to introduce yourself to the podcast? Abby Hepp: Hi my name is Abby Hepp, I am majoring in Communication Media at NC State and I'm currently a sophomore. EB: Awesome! So we're going to get right into it! Today we're going to be talking about some of your adventures that you've been going on in the past few years and using to inspire other people as well, so let's start with- how did you become involved in outdoor activities and adventuring initially? AH: First of all, thank you for having me and initially will growing up, I would say my family was moderately active and you know I kind of had the typical playing outside with the neighbors childhood. -

Spanish Peaks Wilderness
Mt. Bierstadt Field Trip Trip date: 6/17/2006 Ralph Swain, USFS R2 Wilderness Program Manager Observations: 1). The parking lot was nearly full (approximately 35 + vehicles) at 8:00 am on a Saturday morning. I observed better-than-average compliance with the dog on leash regulation. Perhaps this was due to my Forest Service truck being at the entrance to the parking lot and the two green Forest Service trucks (Dan and Tom) in the lot! 2). District Ranger Dan Lovato informed us of the District’s intent to only allow 40 vehicles in the lower parking lot. Additional vehicles will have to drive to the upper parking lot. This was new information for me and I’m currently checking in with Steve Priest of the South Platte Ranger District to learn more about the parking situation at Mt. Bierstadt. 3). I observed users of all types and abilities hiking the 14er. Some runners, 14 parties with dogs (of which 10 were in compliance with the dog-leash regulation), and a new- born baby being carried to the top by mom and dad (that’s a first for me)! Management Issues: 1). Capacity issue: I counted 107 people on the hike, including our group of 14 people. The main issue for Mt. Bierstadt, being a 14er hike in a congressionally designated wilderness, is a social issue of how many people are appropriate? Thinking back to Dr. Cordell’s opening Forum discuss on demographic trends and the growth coming to the west, including front-range Denver, the use on Mt. -

Late Pleistocene Glacial Equilibrium-Line Altitudes in the Colorado Front Range: a Comparison of Methods
QUATERNARY RESEARCH l&289-310 (1982) Late Pleistocene Glacial Equilibrium-Line Altitudes in the Colorado Front Range: A Comparison of Methods THOMAS C. MEIERDING Department of Geography and Center For Climatic Research, University of Delaware, Newark, Delaware 19711 Received July 6, 1982 Six methods for approximating late Pleistocene (Pinedale) equilibrium-line altitudes (ELAs) are compared for rapidity of data collection and error (RMSE) from first-order trend surfaces, using the Colorado Front Range. Trend surfaces computed from rapidly applied techniques, such as glacia- tion threshold, median altitude of small reconstructed glaciers, and altitude of lowest cirque floors have relatively high RMSEs @I- 186 m) because they are subjectively derived and are based on small glaciers sensitive to microclimatic variability. Surfaces computed for accumulation-area ratios (AARs) and toe-to-headwall altitude ratios (THARs) of large reconstructed glaciers show that an AAR of 0.65 and a THAR of 0.40 have the lowest RMSEs (about 80 m) and provide the same mean ELA estimate (about 3160 m) as that of the more subjectively derived maximum altitudes of Pinedale lateral moraines (RMSE = 149 m). Second-order trend surfaces demonstrate low ELAs in the latitudinal center of the Front Range, perhaps due to higher winter accumulation there. The mountains do not presently reach the ELA for large glaciers, and small Front Range cirque glaciers are not comparable to small glaciers existing during Pinedale time. Therefore, Pleistocene ELA depression and consequent temperature depression cannot reliably be ascertained from the calcu- lated ELA surfaces. INTRODUCTION existed in alpine regions (Charlesworth, Glacial equilibrium-line altitudes (ELAs) 1957; ostrem, 1966; Flint, 1971; Andrews, have been widely used to infer present and 1975). -
