Making an Impact

If you dig deep enough anywhere on the planet you’ll eventually hit a thin layer of clay called the K-T boundary (a few pieces of which are shown the in the photo).  This band was laid down about 66 million years ago and marks the end of the Mesozoic Era.  It has been found at over 100 different locations on earth.

So how did a layer of sediment end up covering the entire planet, including the oceans?  The answer is Chicxulub.

You may not know the name, but Chicxulub had a huge impact on the planet earth (pun intended).  Chicxulub was an asteroid about 6 miles wide that impacted the Yucatan Peninsula.  It hit with the force of a billion atomic bombs.  It triggered firestorms that raged across the planet and tsunamis that were thousands of feet high.  The dust that it ejected into the atmosphere (which later became the K-T boundary) would have blocked sunlight for years.  And since the asteroid hit a bed of gypsum, this caused massive amounts of sulfur trioxide to enter the atmosphere.  Once it the atmosphere the sulfur trioxide reacted with water to become sulfuric acid – triggering acid rain storms that blanketed the planet.

There are few things more powerful than Chixulub, but one of those things happens to be my dad.

He may not be famous, but the impact that he has had on my life cannot be measured.  Since before my birth he has loved me unconditionally.  From my earliest years I have tried to mimic him.  I remember snuggling up to him as a very young child and trying to make my breathing perfectly mirror his.  I worked hard in school because I wanted to be as smart as he is and I always knew that no matter how tricky my homework was it always seemed so easy to him.  Even my goofy sense of humor is my dad’s fault.

Chicxulub was a major force of destruction while my dad has done nothing but build me up.  But they do have one thing in common: Chicxulub happened to contain extremely high levels of iridium, the rarest of all the precious metals (about 12 times rarer than gold).  It also happens to be the most corrosion-resistant metal on the planet.  So when you are digging and eventually hit the K-T boundary you can be sure that it contains iridium.

Oftentimes I feel like a complete mess and pretty clueless as a dad, but I know that if I dig deep enough I’ll find that layer of iridium – and I’ll know that it came from my dad.
