Looking around Walker began to see some grey and jagged looking egg shapes. They would easily be confused for some strange rock formations if he didn't know this was a rock horned viper nesting area.
The next shapes he made out were some points and curving formations. These were also slightly moving as if sleeping. This was clearly the rock horned vipers that were burying themselves under the sand and dust to rest or hide away. The spikes were a perfect camouflage for them so that they wouldn't be seen by prey or predators. The large spikes at one end would be the rock horn that gave them their names.
