Cara Ascarrunz - Junior Ranger Crew Leader

Photo of Cara Ascarrunz

Throughout my life, I have been drawn to the field of biology and natural resources. Growing up in Louisiana, wild nature was abundant, and I carried that passion towards obtaining a degree in Biology with minors in Spanish and International Studies from Truman State University in Kirksville, Missouri. An REU internship through CU Boulder brought me to the area during the summer of 2012 for marmot ecology research, and I fell in love with the area and decided to move to Boulder in 2013.

Since moving to Boulder, I have worked in various jobs related to outdoor education including an environmental nonprofit (Environment for the Americas), Colorado Parks and Wildlife, and the Boulder OSMP Junior Ranger Program. The general history and legacy of Boulder OSMP inspires me to bring my passion every day to work within such an amazing organization. In my spare time, I love hiking, camping, and exploring beautiful Colorado. You may also find me on a tennis court, in my room reading, or practicing guitar. I'm excited to learn more about OSMP projects involving forest ecology and invasive plant management! 

Hannah Filley - Junior Ranger Assistant Crew Leader

Photo of Hannah FilleyAfter three years as a Junior Ranger, I’m so happy to return to the program as an Assistant Crew Leader. Born and raised in Boulder, I’m eager to continue giving back to the trails I grew up hiking. This summer I am excited to use trail gauges, expand my understanding of OSMP land restoration, and return to muddy boots and fulfilling work. My goal is to ensure my Junior Rangers have as much fun in the program as I did, while also teaching them about the land and the value of hard work. My favorite fact I’ve learned during my time in the program is that almost all tree species growing in Boulder today are invasive. Aside from my love of drainage dips and mountain air, I play Ultimate Frisbee, enjoy creative writing, and am interested in pursuing education and/or sports medicine. After the season ends, I will return to Walla Walla, Washington where I will continue my undergraduate degree in English at Whitman College.

Logan Garby - Junior Ranger Assistant Crew Leader

Photo of Logan GarbyGrowing up within 100 feet from Boulder’s Open Space, I learned immense appreciation for OSMP. After 3 years of being a Junior Ranger, I am excited to continue fostering stewardship. I enjoy hiking, mountain biking, downhill skiing and playing tennis. I graduated from Fairview High School in May of 2016 and am honored to be attending Cal Poly at San Luis Obispo in the fall. My plans for study include Mechanical or Aerospace Engineering. I love learning and am excited to learn more about OSMP. I am a fun-loving, easy-going person who always has a positive attitude and is eager to help in whatever way I can.

Preston Hopkins - Junior Ranger Crew Leader

Photo of Preston HopkinsI grew up frolicking in the vast fields and forest of Northern Wisconsin. I have a B.S. in Outdoor Education from Northland College in Ashland, WI. I have more than five years of experiential education experience ranging from the remote backcountry of Montana’s Bob Marshall Wilderness to the lush rainforest of Hawaii. I am excited for the opportunity to explore, preserve, and teach in Boulder’s Open Spaces and Mountain Parks. In my first year with the Junior Ranger program, I am thrilled to utilize Boulder’s vast trails and wilderness to assist in creating the next generation of environmental stewards. When I am not enjoying Boulder’s 45,000 acres of OSMP, you can find me playing music with the Boulder Concert Band, running, camping, hiking, or cheering on the Green Bay Packers. 

Linn Kelley - Junior Ranger Assistant Crew Leader

Photo of Linn KelleyI’ve lived in Boulder all my life and have a great appreciation for the outdoors. This is my fifth year with OSMP, and after four years as a Junior Ranger, I am excited to be a leader in the program for the first time. I love the trails and open space because I grew up hiking in Boulder, and I spend lots of time hiking and hammocking in the foothills. I think it’s cool that falcons nest in the flatirons near the start of Bear Canyon, and can’t wait to learn more about the animals and plants on open space! In my free time I play the cello and go skiing.

LeeMichael Krieger - Junior Ranger Crew Leader

Photo of LeeMichael KriegerI am a self proclaimed professional adventurer and avid outdoorsman. I was born and raised in Barkhamsted, Connecticut, a rural town that's home to about 3,000 residents and almost an equal number of white tailed deer. From a young age this tiny community inspired me to discover a passion for wild places. I left in 2009 to study at Northern Arizona University where I received my Bachelors of Science in Parks and Recreation Management. The experience opened my eyes to a reality I had not thought possible. Adventuring was not only a profession, but a catalyst to self actualization and personal growth. Shortly after graduating, I accepted a job with Thompson Island Outward Bound and spent the next 3 years as a facilitator and guide, working with students in the Boston harbor islands. I was humbled by the impact that natural areas can have on students. I want to give back to these influential places. Thus, my passion for stewardship was born. The Junior Ranger program creates an environment for young adults to become leaders and find a connection with the natural world. More than anything, I'm excited to watch and be a part of the transformation process as Junior Rangers come together and find their own sense of place within the mountains this summer.

Jackson Lombardi - Junior Ranger Program Assistant

Photo of Jackson LombardiI’m a current undergrad at CU Boulder studying psychology and business. At the end of this season I’ll have spent 3 years in Junior Ranger yellow and 3 years as staff for OSMP. I grew up exploring Boulder’s open space and feel so fortunate to be working on it now. Protecting Earth’s natural resources both impassions and motivates me. I am an avid skier in the winter and trail runner in the summer. I can’t wait to spend another season with the Junior Rangers and continue giving back to the people and places that have given so much to me.

Justin Long - Junior Ranger Assistant Crew Leader

Photo of Justin LongI have grown extensively during my time with the Junior Ranger program. My work experience started in Junior Rangers when I was 14 and I have done it almost every summer since. I have always been an independent entrepreneur and I have had my own landscaping and yard work business. I graduated from Boulder High School in 2014 and went on to pursue my education at University of Colorado Denver for Guitar performance and Music Business. I will be a junior in college and I have started my career playing music in local bands around town. This is my sixth summer with OSMP and I am thrilled to be returning in full force. I am excited to learn more leadership skills as well as how to educate and share my passion for nature with the Junior Rangers. I see myself working with Boulder OSMP in the future. I want to figure out how I can utilize my skills and passion for music to better the world and promote sustainability.

Liam McDonald - Junior Ranger Assistant Crew Leader

Photo of Liam McDonaldThis is my fifth year in the Junior Ranger program, and my first as an Assistant Crew Leader. As a Boulder native, I was raised with a passion for OSMP land and the outdoors. Even after eighteen years I am still in awe of the amazing scenery and recreational opportunity that Boulder offers. When not on the trails, you can often find me climbing in Boulder Canyon, playing with dogs, or in the garden. I’m excited for another summer of working with like minded kids in the outdoors. Next year I will be studying physics/engineering at the University of Utah in Salt Lake City, but I’ll never forget the experiences and knowledge I have gained from the program.

Jack McAlpine - Junior Ranger Assistant Crew Leader

Photo of Jack McAlpineI have spent the majority of my life in Boulder. Throughout this time I gained an incredible appreciation for the outdoors and the stunning landscapes that Boulder and the surrounding areas supply. This will be my fifth year with the Junior Rangers. I was a Junior Ranger for three years and was an Assistant Crew Leader last year. My sophomore year of college at the University of Idaho begins this fall, and I hope to obtain a bachelor’s degree in chemical engineering in 2019. When I am not too busy working or studying, I enjoy climbing, hiking, and spending time with good friends. 

Calvin Mooz - Junior Ranger Assistant Crew Leader

Photo of Calvin MoozMy passion for giving back to the community has led me to my first year as a Junior Ranger Assistant Crew Leader. I just graduated high school in May, and, growing up in Boulder, I have been an OSMP user my whole life. I was a Junior Ranger for three years working on over the 150 miles of trail. In my free time I enjoy playing beach volleyball, pickup soccer, pickup basketball, and playing with my dog.

Laila Murfin - Junior Ranger Program Assistant

Photo of Laila MurfinI am so excited to be bringing my passion for forestry, outdoor education, youth empowerment and service learning to a second season with OSMP's Junior Rangers. My own youth corps opportunities shaped my life in countless ways; I feel grateful to have the opportunity to support others in similar launching experiences. Working for two years with WA Conservation Corps led to several stints with the USFS working in wilderness, fire, and trails; volunteer coordination in local food systems in Reno, NV; and now to Junior Rangers. I am intrigued by the biodiversity of the OSMP landscape, and Boulder's commitment is to its public lands, and can't wait to learn more about the unique ecosystem this summer. When I am not at work on the trails you can find me practicing AcroYoga at the Farmer's Market, climbing, or cooking delicious feasts. I look forward to bringing my Junior Ranger experience forward into my career as a counselor, incorporating wilderness therapy with body based and creative arts therapies. 

Greg Over - Junior Ranger Crew Leader

Photo of Greg OverMy name is Gregory Over, and I’m a Colorado native grateful to be serving my fourth season as Crew Lead for the Junior Ranger program. I graduated from Colorado State University in winter of 2014 where I earned my Bachelors of Science in natural resources and environmental communications. I’ve been working with youth in the outdoors since I was sixteen. I am excited to continue building my service learning experience with OSMP where an innate sense of stewardship for the natural environment, integrity, and unique work culture comes standard. As a member of the last generation to know what it’s like to grow up without the plugged-in, WiFi distraction of the digital world, I feel a sense of duty to help connect youth with the unique landscape around them. I learn fun facts about our open space every day, but my favorite as of late has been geological.  Did you know the Third Flatiron is 1,400 feet - a few higher than the Empire State Building (and it’s been summited by a climber on roller blades)? On the weekends I enjoy working on cars, camping in the Colorado backcountry, and occasionally brewing my own craft beer. I hope to extend my work with OSMP past the summer in a role that continues to serve the trails and people of Boulder. I couldn’t be more excited to be fostering future land stewards within the Junior Ranger program this summer. 

Louis Simpson - Junior Ranger Crew Leader

Photo of Louis Simpson

My name is Louis Simpson and I am a native of Boulder, working in my sixth season with the Junior Ranger program. This is my second time as a Junior Ranger Crew Leader and graduated from the program in 2011. I have spent the last four years in Washington, DC working towards my bachelor’s in biomedical engineering, and graduated May of 2016. I have a focus in rehabilitation engineering and will pursue a master’s degree with anticipated graduation in spring of 2017. I’m very passionate about modeling service leadership and inspiring stewardship within the Junior Rangers. I was able to serve in this youth development in a number of different roles while in school, serving as a student minister on campus, starting my own basketball after school outreach with the local high school, and leading a number of different social events for the underclassmen. One interesting fact that I learned on OSMP is that the golden banner plant needs a bumble bee to pollinate it because the leaves are held together too strongly for a normal bee. In high school I won a state championship for baseball and even got to pitch nearly a complete game at Coors’ field. I enjoy playing guitar and singing, and am beyond excited to see the Junior

Rangers grow in their trail skills, teamwork, and excitement for the outdoors.
