This is the core program for Indigo Mountain.  The organization provides a sanctuary for a variety of species including wolfdogs and black bear.  Currently, the sanctuary is home to over 40 animals that have been displaced, surrendered or confiscated.  For some animals who have been deemed un-adoptable the sanctuary is a permanent home while others are rehabilitated physically and behaviorally and placed in loving homes.

Charting impact

Four powerful questions that require reflection about what really matters - results.

The Center has a twofold mission: 1) To provide a permanent sanctuary and a last chance for a life of compassion, love, dignity and respect to animals who have been abused, abandoned, displaced, impounded, neglected, exploited or have become surplus. 2) To provide a variety of educational products and programs that create public awareness for wildlife and to provide resources to people who wish to raise the bar in animals care for their captive-born wildlife, exotic animals and alternative pets.

1) Indigo Mountain has created a facility where animals have the opportunity to thrive in a life-long sanctuary. The sanctuary provides enriched, comfortable habitats with a high level of care for the health and wellbeing of each of the animals in residence. We don’t just save their lives; we rehabilitate them physically and emotionally so they can maximize their potential and lead the best lives possible. 2) Indigo Mountain works cooperatively with governmental agencies, animal shelters and individuals needing to surrender animals. 3) Discover Wildlife lectures and outreach programs are offered to a number of schools, parks, clubs, and neighborhood organizations. These programs foster a desire to preserve wildlife and learn about the important role these animals play in our world. 4) The Companions for Life program provides help and resources to individuals to aid them in taking better care of their pets and to keep them out of shelters and rescue. 5) Indigo Mountain provides behavioral evaluations and phenotyping services to governmental agencies and shelters.

Indigo Mountain’s strategic plan concentrates on its mission, goals and objectives and consistently re-evaluates our program and our capabilities. 1) The sanctuary has created habitats designed to meet the needs of the animal’s physical, psychological and social needs. 2) To provide a permanent home for those species for which the sanctuary has sufficient expertise and facilities. 3) To partner and build affiliations with governmental authorities, parks, schools, clubs and organizations to reach a large number of people interested in animals

In its 22 year history Indigo Mountain has continued to grow from a small animal rescue organization to permanent sanctuary housing over 40 wolfdogs and black bears. The education arm of the organization continues to develop new programs that are a fun way for kids of all ages to tame their curiosity for the wild world. The programs foster a desire to preserve wildlife and learn about the important role these animals play in our world. The sanctuary has developed partnerships with colleges to provide internships and learning opportunities for students to learn more about animal care.

Balance sheet

Fiscal Year: Jul 01 - Jun 30

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
