You confused a completely different one that's in New York City with the one defunct congregation in Utah.
The spelling of congregation is different. The ones buried in Sharey Tzedick cemetery did not come from New York. They came mostly from Russia. Congregation Sharey Tzedick failed and members went back to Congregation B'Nai Israel, now merged into Congregation Koi Ami.
The names Rider does not show up in Sharey Tzedick cemetery at all. West Section is in northwest section of the City Cemetery. http://www.slcgov.com/cemetery/cemetery-maps
- click on the map to see enlarged one. You will see there is one marked Jewish cemetery at top left corner, that is Sharey Tzedick, it is not part of the City Cemetery at all.
