S&P 500 nearing the stratosphere

I cannot paste a picture here - so please look at the link below for the long-term S&P 500 PE-ratio.

Findings:
1) Very high levels have become more frequent.
2) We are currently at one of those very high PE points in time - historically these were followed by corrections.
