To the Editor:

The air quality index in Sierra National Forest was recently recorded at 1076! Values over 300 are hazardous. Yosemite, with a hazardous AQI of 681, had to close temporarily.

These are the places my sister, niece and I visited and walked in the pristine forest in June 2019. It was the first time in my life I ever saw such majestic wilderness. Sadly, it might be the last time.
