The Forgotten Active Volcano in Hawaii

The Ancient Volcano in Wyoming; Devils Tower
One theory of the formation of Devils Tower is it the eroded remnant of a lake of lava. the lava cooled from the top down forming hexagonal columns that resisted erosion better than the surrounds leaving the butte.

The Most Recent Volcanic Eruption on Mars; 50,000 Years Ago
Indications of a pyroclastic eruption on Mars in the past quarter million years are evident at Cerberus Fossae volcano. The cause of the eruption has yet (2022) to be confirmed but on possibility is the meteor impact that formed the nearby Zunil Crater.

The Impact Crater in Idaho & Montana; Beaverhead Crater
Approximatly 600 million years ago a 9 kilometer wide asteroid stuck what is now Idaho, then attached to Antarctica. Its impact through debris up to two thousand kilometers away leaving a crater 60 km wide and 12 km deep. This fifth largest known impact may have contributed to the End-Ediacaran extinction which preceded the Cambrian explosion.

The Geologic Oddity in Hawaii; The Great Crack
As magma rises it puts pressure on the crust above. Until the magma finds an outlet it can cause cracks in the crust that can get fairly large. A good place to see them is on the slopes of Hawaii's Kiluea volcano.

The Largest Impact Crater on the Planet; Hidden in Antarctica & 300 Miles Wide
The author posits that a massive asteroid impact that created the hypothesized Wilkes Land Crater under the Antarctic ice may have caused the formation of the Siberian traps that lead to the mass extinction know as the Great Dying, An asteroid impact on the planet Mercury caused a similar effect antipodal to the impact location.

1.2 Billion Years of Rock is Missing; The Mystery of the Great Unconformity
During the Crygenian Period the earth was largely covered with thick ice. Geologists suspect that the ice sheets caused so much erosion that they swept over a billion years worth of deposited rock into the oceans. The result is the Great Unconformity where 520 million year old sandstone appears directly over 1.7 billion year old rock in places like the Grand Canyon.

The Perfect Match

The Perfect Match

Following his calling from God, Patrick McFarlane finds himself homeless, living out of the back of his truck with two wiener dogs. In complete desperation, he places an ad on Craigslist, after his seven year journey to donate a kidney remains unfulfilled. An extremely touching true story of altruism, 'The Perfect Match' documents kidney donor, Patrick McFarlane, through his personal obstacles and modern societal challenges on his path to find a donor program that will accept him, and ultimately find a kidney recipient that will be a perfect match. Regret and redemption are interwoven with Patrick's remarkable ability to laugh at himself and his amazing perseverance in achieving his goal, no matter the cost. This film also explores the themes of medical politics, friendship, religion, and the societal bias that is sometimes placed on us as individuals when we are different than the norm. This film provokes questions regarding our complicated organ donation system and the realities of non-directed donors. It also forces us to take a personal look at one self, and our willingness to save a stranger's life, and the possible societal judgments of those who would. It asks the question of how sane is sane and just because we are different, or have redemption issues, or any other motive, does it make the gift of donation any less powerful or acceptable? I am honored to have documented the incredibly dedicated, emotional journey and heart felt true story of Patrick Mcfarlane, kidney donor, Christian, human, homeless man, father, leader, and hero.
