The 6th Extinction (Sigma Force 10)

Still kneeling at the water’s edge, she waved a hand along the shore’s edge, stirring a floating carpet of blackflies. They rose up in a cloud of buzzing complaint.

“Sick,” said a sullen redheaded teenager as he stepped closer to get a better view.

“Don’t worry. They’re not biting flies.” Jenna motioned a young boy of eight or nine to her side. “But they are creative little hunters. Come see.”

The boy timidly came forward, followed by his parents and the other tourists. She patted the ground next to her, getting the boy to crouch, then pointed to the shallows of the lakebed, where several flies scurried underwater, encased within little silvery bubbles of air.

“It looks like they’re scuba diving!” the boy said with a huge grin.

Jenna matched his smile, appreciating his childish excitement at this simple wonder of nature. It was one of the best aspects of her job: spreading that joy and amazement.

“Like I said, they’re resourceful little hunters.” She stood and moved aside to allow others to get a look. “And it is all those brine shrimp and blackflies that in turn feed the hundreds of thousands of swallows, grebes, cranes, and gulls that migrate through here.” She pointed farther along the shoreline. “And if you look over there, you can even see an osprey nest in that tall tufa.”

More snapshots were taken as she retreated back.

If she had wanted, she could have expanded further upon the unique web of life at Mono Lake. She had barely scratched the surface of complexity of the alkaline lake’s strange ecosystem. There were all matter of odd species and adaptations to be found here, especially in the mud deep in the lake, where exotic bacteria thrived in conditions that would seem to defy logic, in mud so toxic and void of oxygen that nothing should live.

But it did.

Life always finds a way.

Though it was a quote from Jurassic Park, the same sentiment had also been drilled into her by her biology professor back at Cal Poly. She had planned on getting her doctorate in ecological sciences, but instead she had found herself more drawn toward the park service, to be out in the field, to be actively working to help preserve that fragile web of life that seemed to be fraying worse and worse with every passing year.

She retreated to her pickup, leaned her back against the door, and waited for the tour to end. Hattie would take the group back in the bus to the neighboring hamlet of Lee Vining, while Jenna trailed behind in her truck. She was already picturing the pile of baby back ribs served at Bodie Mike’s, the local diner.

From the open window behind her, a wet tongue licked the back of her neck. She reached blindly back and scratched Nikko behind the ear. Apparently she wasn’t the only one getting hungry.

“Almost done here, kiddo.”

A thump of a tail answered her. The four-year-old Siberian husky was her constant companion, trained in search-and-rescue. Pushing his head out the open window, he rested his muzzle on her shoulder and sighed heavily. His eyes—one white-blue, the other an introspective brown—stared longingly toward the open hills. Hattie had once told her that, according to Native American legends, dogs with different-colored eyes could see both heaven and earth.

Whether this was true or not, Nikko’s gaze remained more pedestrian at the moment. A jackrabbit shot across a nearby slope of dry brush, and Nikko burst to his feet inside the cab.

She smiled as the rabbit quickly vanished into the dusky shadows.

“Next time, Nikko. You’ll get him next time.”

Though the husky was a skilled working dog, he was still a dog.

Hattie collected and herded the group of tourists toward the bus, gathering stragglers along the way.

“And Indians used to eat those fly larva?” the redheaded teenager asked.

“We called them kutsavi. Women and children would gather the pupae from the rocks into woven baskets, then toast them up. It’s still done on special occasions, as a rare treat.”

Hattie winked at Jenna as she passed by.

Jenna hid a grin at the kid’s sickened expression. That was one detail of the web of life found here that she had left Hattie to impart.

While the bus loaded up for the return run, Jenna tugged open her truck door and climbed in next to Nikko. As she settled in, the radio squawked loudly.

What now?

She unhooked the radio. “What’s up, Bill?”

Bill Howard was the service dispatcher and a dear friend. Bill was in his mid-sixties but had taken her under his wing when she had first started here. That was over three years ago. She was now twenty-four and had finished her bachelor’s degree in environmental sciences in her spare time, the little that there was. They were understaffed and overworked, but over these past few years, she had learned to love the moods of the lake, of the animals, even of her fellow rangers.

“I don’t know for sure what’s up, Jen, but I was hoping you could take a swing up north. Emergency services relayed a partial 911 call to our office.”

“Give me the details.” Besides acting as curators of the parks, rangers were also fully sworn law enforcement officers. Their duties encompassed a wide variety of roles, anything from criminal investigations to emergency medical response.

“The call came from outside of Bodie,” Bill explained.

She frowned. Nothing was outside of Bodie, except for a handful of gold-rush-era ghost towns and old abandoned mines. That is, except for—

“It came from that military research site,” Bill confirmed.

Crap.

“What was the call about?” she asked.

“I listened to the recording myself. All that could be heard was shouting. No words could be made out. Then the call cut off.”

“So it could be anything or nothing.”

“Exactly. Maybe the call was made by mistake, but someone should at least swing by the gate and make an inquiry.”

“And apparently that would be me.”

“Both Tony and Kate are out near Yosemite, dealing with a drunk-and-disorderly call.”

“All right, Bill. I’m on it. I’ll radio once I’m at the base gate. Let me know if you hear anything else.”

The dispatcher agreed and signed off.

Jenna turned to Nikko. “Looks like those ribs are gonna have to wait, big fella.”

7:24 P.M.

“Hurry!”

Four stories underground, Dr. Kendall Hess pounded up the stairs, followed closely by his systems analyst, Irene McIntire. Red emergency lights strobed at each landing. A siren rang a continual warning throughout the facility.
