“The organization's bylaws were modified in 2023. Significant changes made to the bylaws brought the organization's governance structure into compliance with current nonprofit law and best practices, including replacing the "executive council" with a member-elected board of directors authorized to govern the organization; updating the board committee structure and removing descriptions of membership committees; consolidating three classes of membership into a single class; and providing clarity around board meeting procedures.”
“A draft of the form 990 is provided to the board prior to filing and the president reviews and approves a draft of the form before it is filed.”
“Applies to members of the executive council, committee chairs and employees. These individuals are required to immediately report any suspected appearance of conflict.”
“The president reviews the executive director's performance and adjusts compensation. The executive director reviews other staff positions and adjusts compensation.”
“Governing documents, conflict of interest policy and financial statements are available on the members section of the organization's website. Reasonable requests for financial information and governing documents may be requested at the mazama offices.”
“Other program services 4: other program services 5: stewardship:in addition to recreation activities and education programs, conservation is central to the mazama mission. From the beginning, the mazamas has played a significant role in preserving existing wilderness areas, having been involved in the establishing both crater lake and mt. Rainier national parks, cascade forest reserve, the three sisters wilderness area, and portlands forest park. The mazamas continues this tradition by organizing trail- and crag-tending activities, as well as funding conservation and research grants to qualified non-profits and students each year.”
“Mazamas maintains a mountaineering library of c. 10,000 publications and an extensive collection of historic and notable mountaineering artifacts which are accessed by both members and non-members (researchers, historians, story-tellers, e.g.). Artificats are exhibited in community settings throughout the year and occasionally loaned to historical societies for exhibit.”
“To support the activities of the mazamas.”
