Hello,
The kiddos were climbing around in a tall evergreen today. A fellow parent noticed a mound of bugs that spread out to what you see in the photo. Any idea what they are?

Dear Irja,
That tree is infested with Giant Conifer Aphids in the genus
Cinara.  According to BugGuide:  “If it’s big, and on a conifer, it’s probably Cinara. To identify further, it’s usually necessary to identify the host plant, and consider the geographic range of different species. … The genus is widespread, but individual species are often limited by the range of their hosts.”
