I'm [planning a Yosemite trip for this summer](https://outdoors.stackexchange.com/q/21682/17441). In reading up on [the rules on fire restrictions](https://www.nps.gov/yose/planyourvisit/firerestrictions.htm), I saw this:

> When and where fire restrictions are not in effect, wood fires are allowed in existing fire rings only and prohibited above 9,600 feet in elevation.

We'll be backpacking from [Ten Lakes to May Lake](https://www.nps.gov/carto/hfc/carto/media/YOSEmap1.pdf), which will go above 9,600ft, so I'm excited to have some campfires when we're at the higher points of our trip. However, I'm not entirely clear on what a "fire ring" will look like--google searches show me the kinds of metal things you'd have on a campground or in your backyard.

**What do these "fire rings" look like and--if anyone has Yosemite knowledge--how often will they be along our trail (or where can I go to find this information)?**
