The highly specialized Granite Mountain crew was part of a small community of Hotshots nationwide. There are about 110 of the 20-person teams, mostly stationed west of the Mississippi River.
Prescott Fire Chief Dan Fraijo gave firefighting tools to the deceased men's families, along with flags that had been flown in their honor.
Family members and visiting Hotshot crews also visited a new public overlook Tuesday near where the men were killed. Drivers who stop at the site along Highway 89 near Yarnell will be able to see a flagpole in the distance that marks the site where the Granite Mountain Hotshots were trapped on June 30. The 15-mile stretch of highway reopened Wednesday morning.
The fire is 90 percent contained, but firefighting activity has essentially ended except for making sure that smoldering embers don't re-ignite homes in Yarnell.
Tuesday's memorial was the last of a handful of vigils for the men before the first of 19 funerals.
Biden, whose two sons were saved by firefighters after an accident that killed his wife and daughter, offered the families some solace as he wrapped up his remarks.
"As unbelievable as it is to even fathom ... the day will come when the memory of your husband, your son, or your dad or your brother will bring a smile to your lips before it brings a tear to your eye," he said. "My prayer for all of you is that that day will come sooner than later, but I promise you as unbelievable as it is, it will come."
