MOUNT ST. HELENS lets loose a burst of steam and ash into the atmosphere Tuesday afternoon. The volcano had been in dormancy after a few spectacular eruptions in May and June. MORE ERUPTIONS EXPECTED Latest volcano blast a reminder From AP and UPI VANCOUVER, Wash. - After erup- ting for the first time in six weeks with an 11-mile-high blast, Mount St. Helens revealed a new glowing red crater yesterday - evidence to scientists that the volcano is bound to act up yet again. "The lesson of last night is everyone has to be prudent and understand that a lull is a lull for a time," said U.S. Geological Survey geologist Tim Hait. NO INJURIFS were reported Tuesday night and only a light dusting of ash spread northeastward as the volcano's lava dome, which had begun forming after its third eruption June 12, was blown 11 miles into the air in three spectacular, pulsating eruptions. The mountain was very quiet yester- day, with no seismic activity reported and only a very slight steam plume wafting from the crater. "You can say the volcano will erupt again. That is a certainty," he said. "But day to day, hour to hour, you can't say. What is says is Mother Nature is a lot more complicated than we can Free Press truckers ratify new contract figure out. .. What it proves is that we're not all smart." HAIT SAID less ash and gases spewed from the mountain Tuesday than in the mountain's earlier blasts of May 18, May 25 and June 12. He said the latest series of blowouts followed a dif- ferent pattern than the earlier erup- tions in that no harmonic tremors, in- dicating movement of molten material within the mountain, were detected before the bursts. "There's still no way that we can tell what's going to happen, simply no way," Hait said. The appearance of the huge~ mushroom-shaped cloud Tuesday caused a massive rush-hour traffic jam in Portland, Ore., 50 miles to the south, as office workers stopped to stare at the spectacular sight. In Seattle, residents flocked to the city's hills to watch and the Space Needle was packed with spectators. THE NATIONAL Weather Service reported the bulk of the ash cloud was over southern Saskatchewan early yesterday. A light ash fallout was reported at Lethbridge, Saskatchewan. Some ash was reported in eastern Washington and in parts of Idaho, Mon- tana, British Columbia and Alberta. A geologist who flew over the volcano yesterday in a U.S. Forest Service plane described the new crater as a "large, glowing pit," according to Charlotte Martin, U.S. Forest Service spokeswoman. A PYROCLASTIC flow of superheated gases and ash overflowed from the north side of the crater and sped six miles north to the shores of Spirit Lake, Hait said. The flow went about the same distance, but was much smaller in volume than that which took the same course during the June 12 eruption. Eastern Washington was dusted with ash by the eruption Tuesday, and the Washington State Patrol issued a travelers' advisory. The hardest-hit community was Colville, with an eighth of an inch. A 30-mph speed limit was imposed for Colville and Stevens County. But residents were more concerned with the sweltering heat - they couldn't turn on their air conditioners for fear of having them ruined by ash. The ash drifted across northern Idaho and Montana and yesterday stretched from the Continental Divide east to southern Saskatchewan. DETROIT (UPI) - Detroit Free Press circulation workers and truck drivers overwhelmingly ratified a new three-year contract yesterday, ending a 12-day strike that crippled the morning newspaper. Free Press officials said the newspaper, forced to publish a unique joint-masthead edition with the rival Detroit News through much of the strike, would resume full publication with Friday's edition. ALL BUT a handful of the 400 to 500 members of Teamsters Local 372 at- tending a midday ratification meeting stood when asked if they supported the new pact, recommended for approval unanimously by union leaders. Reporters, editors and other em- ployees represented by The Newspaper Guild, which had been honoring the lines, then began returning to the desks they had vacated after the 550 Team- sters walked out July 12. "I am enormously glad to see this newsroom looking like it's a newsroom again," Free Press Executive Editor David Lawrence said. Lawrence said the Free Press plan- ned one more "integrated" edition with The News but "we are already begin- ning work on Friday's paper and papers beyond." The walkout came just two days before the start of the Republican National Convention and disrupted Free Press coverage of the GOP gathering that had been planned for more than a year. The new pact was basically the same economically as one already ratified by Teamsters at The News but whose rejection sparked the Free Press strike. Union members went along with the urging of their leadership but still were split about the contract.
